ConspectusMolecular recognition is one of the fundamental events in biological systems, as typified by enzymes that enable highly efficient and selective catalytic reactions through precise recognition of substrate(s) and cofactor(s) in the binding pockets. Chemists therefore have long been inspired by such excellent molecular systems to develop various synthetic receptors with well-defined binding sites. Their effort is currently being devoted to the construction of not only molecular receptors but also self-assembled host compounds possessing connected cavities (pores) in the crystalline frameworks to rationally design functional porous materials capable of efficiently adsorbing molecules or ions at binding sites on the pore walls. However, it is still challenging to design multiple distinct binding sites that are precisely arranged in an identical framework, which is currently one of the most important targets in this field to realize elaborate molecular systems beyond natural enzymes.In this Account, we provide an overview of porous crystals with well-defined molecular recognition sites. We first show several strategies for arranging macrocyclic binding sites in crystalline frameworks such as metal-organic frameworks, porous molecular crystals, and covalent organic frameworks. Porous metal-macrocycle frameworks (MMFs) that we have recently developed are then described as a new type of porous crystals with well-defined multiple distinct binding sites. The MMF-1 crystal, which was developed first and is composed of four stereoisomers of helical PdII 3-macrocycle complexes, has one-dimensional channels with dimensions of 1.4 nm × 1.9 nm equipped with enantiomeric pairs of five distinct binding sites. This structural feature of MMF-1 therefore allows for site-selective and asymmetric arrangement of not only single but also multiple guest molecules in the crystalline channels based on molecular recognition between the guests and the multiple binding sites. This characteristic was also exploited to develop a heterogeneous catalyst by non-covalently immobilizing an organic acid on the pore surface of MMF-1 to conduct size-specific catalytic reactions. In addition, adsorption of a photoreactive substrate in MMF was found to switch the photoreaction pathway to cause another reaction with the aid of photoactivated PdII centers arranged on the pore walls. Furthermore, the dynamic, transient process of molecular arrangement incorporated in MMF-1 has been successfully visualized by single-crystal X-ray diffraction analysis. The formation of homochiral MMF-2 composed of only (P)-or (M)-helical PdII 3-macrocycle complexes is also described. Thus, macrocycle-based porous crystals with a complex structure such as MMFs are expected to serve as novel porous materials that have great potential to mimic or surpass enzymes by utilizing well-defined multiple binding sites capable of spatially arranging a catalyst, substrate, and effector for highly selective and allosterically tunable catalytic reactions, which can be also visualized by crystallographic analysis because of their crystalline nature.

The preparation and characterization of the three ferrocene based dithiolane complexes [(eta5-C5H5) Fe(eta5-C5H4)NHC(O)(CH2)4CHS 2CH2CH2]1, [(eta5- C5H5)Fe(eta5-C5H 4)CH2OC(O)(CH2)4CHS2CH 2CH2] 2 and [(eta5-C5H 5)Fe(eta5-C5H4)NHC(O)(CH 2)CHS2CH2CH2] 3, with different spacer groups between the ferrocenyl moiety and the dithiolane unit, are reported. The complexation of 1 and 2, using the oxidative addition of the S-S bonds to Pt(0), is also described, leading to the square planar Pt(II) complexes [Pt(PPh3)2(S2CH2CH 2CH-kappa2-S,S)(CH2)4C(O) NH(eta5-C5H4)Fe(eta5-C 5H5)] 4 and [Pt(PPh3)2(S 2CH2CH2CH-kappa2-S,S)(CH 2)4C(O)OCH2(eta5-C 5H4)Fe(eta5-C5H5)] 5, respectively. The reduction of the S-S bond in 1 and 2 yields the corresponding dithiols; these can be deprotonated and treated with ClSiMe3 to prepare [(eta5-C5H5)Fe(eta5- C5H4)NHC(O)(CH2)4CH(SSiMe 3)CH2CH2(SSiMe3)] 7 and [(eta5-C5H5)Fe(eta5-C 5H4)CH2OC(O)(CH2) 4CH(SSiMe3)CH2CH2(SSiMe 3)] 9, respectively. The complexes were characterized via NMR and UV-Vis absorption spectroscopy, cyclic voltammetry and single crystal X-ray diffraction for 1 and 4.

Reference of 1273-86-5, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In an article, 1273-86-5, molcular formula is C11H3FeO, belongs to iron-catalyst compound, introducing its new discovery.

A series of primary ferrocenylalcohols, Fc-(CH2)m-OH with m = 1-4 and Fc = ferrocenyl, was synthesised by reduction of the appropriate ferrocenylcarboxylic acids, Fc-(CH2)n-COOH (n = 0-3) and the ester methyl 4-ferrocenylbutanoate with LiAlH4, the reduction of the gamma-ketoacid ferrocylpropanoic acid, Fc-CO-(CH 2)2-COOH, with AlCl3/LiAlH4, and the reduction of ferrocenylcarboxaldehyde, FcCHO, with NaBH4. The secondary ferrocenyl alcohols CpFe(C5H4-CH(OH)-CH 3) and Fe(C5H4-CH(OH)-CH3) 2 were obtained by NaBH4 reduction of acetyl and diacetyl ferrocene. The different reduction methods are compared. The electrochemistry of the alcohols was studied by cyclic voltammetry in CH3CN/0.1 M N(nBu)4PF6 utilising a platinum working electrode. The ferrocenyl group showed reversible electrochemistry with the formal reduction potential (Eo? versus Fc/Fc+) of the ferrocenyl group inversely proportional to side chain length. The influence of the side chain length on Eo? was more pronounced for the acids because the electron-withdrawing properties of the carbonyl group is stronger than that of the alcohol group. Ion pairing was found to play a major role in the electrochemical behaviour of ferrocenylmethanol, Fc-CH 2-OH.

A copper-catalyzed, enantioselective method for the borylallylation of vinyl arenes is reported. The reaction produces enantioenriched and functionalized organoboron compounds by sequentially incorporating boryl and allyl groups onto the C – C bond of vinyl arenes. Copper-catalyzed borylative coupling of vinyl arenes with allyl phosphates successfully proceeds in a regio- and enantioselective manner in the absence of a palladium cocatalyst.

The influence of different substituents in the Cp-ring and at the carbinol C atm on the character and stability of H bonds in crystals of FcCHROH and 9FcCHROH, Fc = C5H5FeC5H4; 9Fc = C5Me5FeC5Me4, (R = H, CH3, C6H5, C6F5) was studied by IR spectroscopy specifically in the nu(OH) region.In the crystals, molecules associate predominantly via intermolecular OH…O bonds.However, in some of the 9FcCHROH complexes, the intermolecular O-H…?(Cp) H bonds are also formed.The major type of self-association in compounds with R = Mes is OH…?(Mes) H-bonding.It was found from the X-ray structural data for the 9FcCHMesOH that the Mes plane is almost perpendicular to each Cp ring plane.No intermolecular OH…O bonds are formed because of intramolecular shielding of the OH group.The stability of the intermolecular hydrogen bonds is determined by steric rather than electronic factors, the most stable intermolecular hydrogen bonds being formed in the case of primary carbinols.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-86-5
