| 摘要 |
<p>The hydrocarboxylation of alkynes with CO and a carboxylic acid in the presence of a catalyst prepared by combining a compound of divalent palladium and a tri-organic phosphine is carried out by using a ratio mol phosphine per gramatom of palladium of more than 15 and, preferably, in the presence of benzenephosphonic acid.</p> |
