A process for saturating or partially saturating and/or extending the carbon chain length of an unsaturated organic compound comprises contacting said compound with hydrogen and/or carbon monoxide in the presence as catalyst of a complex or compound of a platinum group metal, and an unsymmetrical biphosphine of general formula A-(CH2)n-B in which A and B are different phosphine moieties, A having the formula R2P and B having the formula either R'2P or RR'P where R represents an aryl group and R' represents an aralkyl, alkaryl or alkyl group and n is an integer between 1 and 10 inclusive, or an unsymmetrical monophosphine of formula R2R'P where R and R' are as defined above. |
