Abstract:
A process for the bisalkoxycarbonylation of olefins comprising the step of reacting an olefin with an alcohol, oxygen and carbon monoxide in the presence of a catalyst for the bisalkoxycarbonylation of olefins comprising a noble metal compound and a phosphine chalcogenide of the following formula (1): ##STR9##wherein each of R.sup.1, R.sup.2 and R.sup.3 is, independently, an alkyl group or an aryl group each of which optionally has a substituent, and A is a Group 16 element of the Periodic Table; and R.sup.1, R.sup.2 or R.sup.3 are optionally combined, directly or through a bridging group, with one another where the groups to be combined are optionally attached either to the same phosphorus atom or to a different phosphorus atom.
