Carboxylic acid esters are produced by reacting (i) carbon monoxide, (ii) a compound of the formula M(OR)x wherein M is either boron, silicon, aluminium, 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 aluminium and the halide moiety is chloride, there is preferably added a source of iodide.
羧酸酯是通过以下反应制得的:(i) 一氧化碳;(ii) 式 M(OR)x 的化合物,其中 M 为硼、硅、铝、钛或锆,x 为 M 的化合价,R 为烃基;(iii) 烃基卤化物,其中卤化物为溴化物、氯化物或碘化物。当 M 为硼、硅或铝且卤化物分子为氯时,最好添加碘源。
