Research Abstract

We investigated dehydrocoupling reactions of boron compounds, which proceed via a transition metal. borane s complex. In this study, we obtained the following results.(1) Half-sandwich carbonyl complexes showed a low catalytic activity in this type of reactions,(2) Reaction intermediates, secondary amine. borane complexes and aminoboraneσcomplexes, were isolated using an electron-rich ruthenium system, and(3) Behaviors of borane in the coordination sphere in the course of the reaction was clarified by deuterium labeling experiments.
