ABSTRACT:
Carboxylic acid esters or amides are obtained from aryl, heterocyclic, vinylic, ethynylic, and benzylic halides and substituted derivates thereof, by reacting same with an alcohol or primary or secondary amine and carbon monoxide, in the presence of a palladium catalyst and if necessary a tertiary amine at about 20.degree.-150.degree. C and from about a half to about 100 atmospheres pressure. A typical example is the conversion of bromobenzene into n-butyl benzoate at 100.degree. C and one atmosphere of carbon monoxide in the presence of tri-n-butyl-amine and a catalytic amount of PdBr.sub.2 [P(C.sub.6 H.sub.5).sub.3 ].sub.2.
