Abstract
Carboxylic acid esters are produced by reacting (i) carbon monoxide, (ii) a compound of the formula M(OR).sub.x wherein M is either boron, silicon, aluminum, titanium or zirconium, x is the valency of M and R is a hydrocarbyl group and (iii) a hydrocarbyl halide, wherein the halide moiety is bromide, chloride or iodide, in the presence of a catalyst comprising one or more of the metals rhodium, iridium and cobalt in either elemental or compound form. When M is boron, silicon or aluminum and the halide moiety is chloride, there is preferably added a source of iodide.
