Carbonylation catalyst

摘要

The invention provides a carbonylation catalyst for carbonylating olefins, said catalyst containing an organometallic complex containing gold metal. The catalyst may be in an unsupported homogeneous form. The organometallic gold complex containing gold metal may be a monometallic gold complex. The carbonylation catalyst may be a hydroformylation catalyst for hydroformylating olefins to aldehydes. The invention also provides a carbonylation process using said catalyst.
