Abstract
This invention relates to a composition comprising a compound having a formula of M2(CO)m(PF3)n, wherein M is a group 9 metal (such as cobalt), m is 1, 2, 3, 4, 5, 6, or 7, n is 1, 2, 3, 4, 5, 6, or 7, and the sum of m and n is 8, that may be used as a hydroformylation pre¬catalyst for converting (such as hydroformylating) olefinic feeds, especially complex feeds comprising internal olefins and high degrees of branching.

A composition comprising a compound having a formula of:
- M2(CO)m(PF3)n;
- wherein M is a group 9 metal, m is 1, 2, 3, 4, 5, 6, or 7, n is 1, 2, 3, 4, 5, 6, or 7, and the sum of m and n is 8.
A method comprising:
- contacting an olefinic hydrocarbon with a hydrogen source and a precatalyst comprising a formula of
- M2(CO)m(PF3)n,
- wherein the precatalyst is formed as the reaction product of Co2(CO)8 and PF3 under conditions effective to convert the olefinic hydrocarbon into a hydroformylation reaction product, wherein M is a group 9 metal, at least one M is cobalt, m is 1, 2, 3, 4, 5, 6, or 7, n is 1, 2, 3, 4, 5, 6, or 7, and the sum of m and n is 8;
- and
- forming an active hydroformylation catalyst comprising a compound represented by the formula of
- HCo(CO)m′(PF3)n′;
- from the reaction product under the conditions effective to convert the olefinic hydrocarbon into the hydroformylation reaction product, wherein m′ is 1, 2, or 3, n′ is 1, 2, or 3 and the sum of m′ and n′ is 4.
