| Research Abstract |
Reactivity and catalytic activity of η^3-α-silabenzyl complexes (molybdenum complex1 and tungsten complex 2) bearing a unique η^3-coordination of silicon and two aromatic carbons to the metal center were studied, and we obtained the following results. (1) Reactions of complexes 1,2 with organic molecules (alcohol, ketones, aldehydes, andalkenes) were examined, and we found that the reactions proceed through cleavage of metal-carbon bonds or a silicon-carbon bond of these complexes. (2) We also revealed that complex 1 shows catalytic activity for hydrosilylation of unsaturated organic molecules.
