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.

L'invention concerne des composés que l'on peut nouvellement utiliser en tant que source de monoxyde de carbone, et éventuellement en tant qu'agent réducteur, dans la préparation de complexes carbonyle/métaux de transition. Ces composés correspondent généralement à la formule (I) dans laquelle X¿1?, X¿2? et X¿3? sont semblables ou différents, et représentent soit une base de Lewis, soit un hydrure, et Y représente un groupe donneur sigma. L'invention concerne en outre un procédé de préparation de carbonate de borane ainsi que l'utilisation de H¿3?BCO en tant qu'agent réducteur.
