ABSTRACT:
High yields of aromatic, aromatic acetic and olefinic acids, esters, amides and the like are derived from a process wherein a halo-hydrocarbon is carbonylated in the presence of a palladium catalyst, a hindered amine base and phosphine in excess. The hindered amine base can comprise C.sub.3 -C.sub.10 branched alkyls, cyclic compounds, or mixtures of the above. The preferred amine is N,N-diisopropylethyl amine. The preferred catalyst is PdCl.sub.2 (PPH.sub.3).sub.2 with the excess phosphine generally supplied by a compound of the formula PR.sup.1 R.sup.2 R.sup.3 where R.sup.1, R.sup.2 and R.sup.3 are preferably phenyl.
