This paper describes the synthesis of a new class of [N,P] ligands based on pyrrole with a dimethylamino group as hard donor and a phosphine moiety as soft base. We have also modified the phosphine fragment to change the electronic and steric properties of these ligands. Palladium complex 3a proved to be very efficient in Heck cross-coupling reactions and in intramolecular aryl-aryl couplings of esters and amides. We have demonstrated the applicability and efficiency of this novel catalyst in the total synthesis of the natural product arnottin I.

The reaction of alpha-hydroxyferrocenylalkyl derivatives and vinylferrocene with 1,5-disubstituted tetrazoles in methylene chloride-aqueous acid HX (X = BF4, ClO4) two-phase systems gives a mixture of 1,3,5- and 1,4,5-trisubstituted tetrazolium salts, the fraction of the 1,3,5-isomers prevailing. The synthesized salts are readily dealkylated under the action of bases to give the above starting compounds. Heating of 3(4)-(ferrocenylmethylene)-1,5-pentamethylenetetrazolium and 3(4)-(ferrocenylmethylene)-2-methyl-1-phenyltetrazolium tetrafluoroborates in anhydrous methanol or ethanol in the presence of catalytic amounts of alkali gives rise to ferrocenylcarbinol ethers. Other nuclephiles (pyridine, triphenylphosphine, sodium thiocyanate, sodium p-toluenesulfinate, dibenzoylmethane) also react with the above tetrazolium salts, forming ferrocenylmethylation products. Heating of equimolar amounts of 3(4)-(ferrocenylmethylene)-1,5-pentamethylenetetrazolium or 3(4)- (ferrocenylmethylene)-2-methyl-1-phenyltetrazolium perchlorates with mercury(II) perchlorates in anhydrous ethanol results in mercuration of the starting tetrazolium salts, involving hydrogen substitution in the methylene or methyl groups bound to tetrazolium carbon atoms. The condensation of the same salts with p-N,N-(dimethylamino)nitrosobenzene, leading to azomethine formation, occurs under similar conditions.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1271-51-8, and how the biochemistry of the body works.Related Products of 1271-51-8

Bilayer electrodes consist of conductive electrodes coated with or bonded to two physically discrete polymeric layers which contain two different redox substances having different E0′ values.The redox substance in the inner polymeric film next to the electrode can be oxidized or reduced by the electrode.That in the outer polymer film is constrained, by physical isolation from the electrode, to undergo oxidation or reduction only at electron energies for redox conductivity by the inner film.This arrangement leads to rectified (unidirectional) current flow.Experimental results from bilayer electrodes based on nine different combinations of redox substances in the films are presented to demonstrate the generality of the phenomenon and the ability to fabricate bilayer film.The redox substances include fixed-site redox polymers like poly2+, polyvinylferrocene, poly(4-methyl-4′-vinyl-N,N’-ethylene-2,2′-bipyridinium), and siloxane polymer of N-methyl-N”-(4-(2-(trimethylsilyloxy)ethyl)benzyl)-4-4′-bipyridinium, and (inner film) mobile redox sites like bromide, hexachloroiridate, and benzophenone.Various mechanisms are considered for bilayer electrode nonidealities which appear as a leakage of redox state trapped in the outer film, an a theory describing voltammeric properties of bilayer electrodes is compared to experimental results.

Two novel isoxazoline N,N-bidentate ligands with ferrocene backbone have been synthesized and employed for the palladium-catalyzed Heck coupling reaction. Among them, 1,3-bis-(5-ferrocenylisoxazoline-3-yl)benzene was found to be thermally stable and a highly effective ligand for Heck coupling reaction in neat water without N2 protection, affording the desired coupling products in good to excellent yield with high diastereoselectivity.

The efficient synthesis of various diborylalkenes such as 1,1-, trans-1,2-, and cyclic 1,2-diborylalkenes from alkenes and diboron was achieved for the first time. Selective preparation of di- and monoborylalkenes was also realized by the appropriate choice of reaction conditions. The reaction was found to proceed via a new mechanism of dehydrogenative borylation through a monoborylpalladium complex bearing an anionic PSiP-pincer ligand as a key intermediate, which realized the efficient borylation without sacrificial hydroboration or hydrogenation of the alkene.
