Research Abstract

We have developed novel transformations only promoted by polynuclear transition metal complexes such as heteroatom-bridged diruthenium complexes. We have newly found the following three topics. (1) We have found enantioselective propargylation of aromatic compounds such as N,N-dimethylanilines, 2-methylfuran, and N-substituted indoles with propargylic alcohols catalyzed by thiolated-bridged diruthenium complexes bearing optically active thiolate ligands to give the corresponding propargylated aromatic compounds in good to high yields with a high enantioselectivity (up to 94% ee). (2) We have found novel reactions between propargylic alcohols and acetone catalyzed by dicationic chalcogenolated-bridged diruthenium complexes to give the corresponding hexadienones in moderate to good yields, in sharp contrast to the formation of γ-ketoalkynes when neutral or monocationic diruthenium complexes are employed as catalysts. (3) We have newly prepared phosphido-bridged diruthenium complexes and investigated their catalytic activity toward reactions of propargylic alcohols with aromatic compounds to give the corresponding α,β-unsaturated ketones in moderate yields. In addition, we have developed novel some reactions catalyzed by thiolate-bridged diruthenium complexes such as vinylic substitution reactions with nucleophiles via butatrienylidene complexes as key intermediates.
