Carbon monoxide source for preparation of transition-metal-carbonyl-complexes

摘要

The present invention relates to compounds that have a novel use as a carbon monoxide source and optionally as a reducing agent in the preparation of transition metal carbonyl complexes. The compounds are in general compounds of formula (I) wherein X₁, X₂ and X₃ are the same or different and either a Lewis base or hydride and Y is a sigma donating group. The invention furthermore relates to a method for the preparation of borane carbonate and to the use of H₃BCO as a reducing agent.
