ABSTRACT:
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, X2and X3are 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.
