Carbon–carbon bond forming reactions of N-bound transition metal α-cyanocarbanions: a mechanistic probe for catalytic Michael reactions of nitriles
摘要:
N-Bound α-cyanocarbanion complexes Ru+Cp(NCCH−R1)(PPh3)2 1 react with electron deficient olefins to afford the conjugate adduct Ru+Cp(NCC−R1CHR2CR3R4)(PPh3)2 2, kinetic studies of which revealed that complex 1-catalyzed Michael reactions of nitriles proceed via transformation of 1 to 2 and subsequent ligand exchange with nitriles.
