Patent ID: 7053242

Claim:
A method of using a compound, the method comprising: preparing a transition metal carbonyl complex using a compound of the following formula as a CO source and as a reducing agent, wherein the using comprises: releasing CO from the compound; and reducing a metal, with which the transition metal carbonyl complex is to be formed, with a hydride substituent attached to boron (B), wherein: X 4 is —H; X 5 and X 6 are substituents which are independently selected from the group consisting of —H, —NH x R y and R, wherein x and y are integers and x+y=3, wherein R is bound by a carbon atom to the nitrogen or boron, respectively; Z is —OH, —OH 2 , —OR or —NHR, wherein R is a substituent that comprises a carbon atom and is bound by the carbon atom to the nitrogen or oxygen, respectively; A is a cation selected from hydrogen and an alkali or alkaline earth metal; n is 0, −1 or −2; and a and m are independently 0, +1 or +2.
