In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. category: iron-catalyst. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde
The invention relates to bi-functionalised metallocenes of general formula (I) where Me=a transition metal, preferably chosen from Fe, Ru and Os, Y and Z, when identical are selected from ?(CH2)n?O?, (CH2)?O?[(CH2)2?O]P? and ?(CH2)q?CONH?(CH2)r?O?, or Y=?(CH2)S?NH? and Z=?(CH2)t?COO?, n=a whole number from 3 to 6 inclusive, p=a whole number from 1 to 4 inclusive, q=a whole number from 0 to 2 inclusive, r=a whole number from 0 to 2 inclusive, s=a whole number from 2 to 5 inclusive, t=a whole number from 3 to 6 inclusive, R and R?=H atoms or are protective groups used in oligonucleotide and peptide synthesis, where at least one of R or R? is protective group used in oligonucleotide and peptide synthesis and R and R? are as defined below: (i) when Z and Y are selected from (CH2)n?O?, ?(CH2)?O?[(CH2)2?O]p? and ?(CH2)q?CONH?(CH2)r?O?, then R and R? are protective groups used in oligonucleotide synthesis and R is a group which can leave a free OH group after deprotection, preferably a photolabile group such as monomethroxythoxytrityl, dimethoxytrityl, t-butyldimethylsilyl, acetyl or trifluroacetyl, and R? is a phosphorylated group which can react with a free OH, preferably a phosphodiester, phosphoramidite or H-phosphonate and (ii) when Y=?(CH2)n?NH? and Z=?(CH2)t?COO?, then R is a protective group used in the synthesis of peptides and is an amino-protecting group, preferably 9-fluorenyloxycarbonyl, t-butoxycarbonyl or benzyloxycarbonyl and R?=H. The above is applied in marking.
Bi-functionalised metallocenes use for marking biological molecules
