| Research Abstract |
As a development of a new hydrosilylation reaction catalyzed by a 16-electron bis(silyl)ruthenium complex A, in which phenyl-substituted alkyne reacts with tertiary silane to give (E)-alkene having a silylated aromatic group, we got the following results (1)-(3). (1)This reaction for various combinations of alkynes and silanes was investigated to elucidate the substituent effect of the substrates on the hydrosilylation. (2)Complex A was found to become a catalyst for hydroboration of an alkyne C≡C triple bond. (3)Related complexes having an N-heterocyclic carbene ligand instead of the phosphine ligand in A were synthesized. Comparison of their catalytic activity on the hydrosilylation revealed how the difference of the ligand influenced on the reactivity.
