ABSTRACT:
This invention relates to the carbonylation of olefins. More particularly it involves the carbonylation of aliphatic conjugated diolefins such as 1,3-butadiene to form adipic acid precursors such as, for example, dimethyl hex-3-ene-1,6-dioate by a process comprising reacting said 1,3-butadiene with carbon monoxide and oxygen in the presence of a hetergeneous palladium catalyst, a copper-containing compound and a lithium-containing compound.
