A Correlation between Redox Behaviour of Fischer-type Carbene Complexes and their Structure and Reactivity
Original language description
A set of about 30 Fischer-type aminocarbene complexes of Cr, W and Fe was synthesized, of general formulae [(CO)nM = C(NMe2)(Ph-p-R)], n = 5 for M = Cr or W , n = 4 for M = Fe; [(CO)nM=C(NMe2)(R')]; [(CO)n-1M =C{N(CH2CH=CH2)(CH2CH =CH2)} (Ph-p-R)] , and[(CO)5Cr=C(NMe2)(Ph-o-Me-p-R)]. Values of oxidation potential Eox, reduction potential Ered and their difference ?E = Eox - Ered were correlated with 1) nature of the central metal, 2) carbene carbon substitution (using the Linear Free Energy Relationship (LFER) approach), 3) coordination sphere geometry 4) bonding abilities of ligands. It was found that the reduction takes place on the carbene carbon atom and Ered depends strongly on the ligand substitution, being influenced by both sterical and inductive effects of the substituents. On the other hand, oxidation is practically independent on the ligand substitution; it is determined mainly by nature of the central metal atom and number of carbonyl groups. The experimental results are c
