| Outline of Final Research Achievements |
Triethylborane adduct of N-heterocyclic carbene (NHC) can act as a carbene precursor for the synthesis of NHC complexes, whereas this compound was not applicable to the preparation of late transition metal complexes. It was found that conversion of “the protecting group” for NHC from BEt3 into AgCl was an efficient method for the preparation of early-late heterobimetallic complexes using the hybrid-type NHC ligand as a bridging mode.
An asymmetric allylic alkylation reaction of 1,3-diphenylprop-3-en-1-yl acetate with dimethyl malonate was examined using C2-symmetric chiral bidentate bis(NHC)-based palladium catalysts. The alkylated product was obtained in 96% yield with a good enantioselectivity (80% ee).
