1-Alkenyiboranes readily prepared by the hydroboration of alkynes react smoothly with carbon monoxide in the presence of palladium chloride and sodium acetate in methanol to give the corresponding α,β-unsaturated carboxylic esters with retention of configuration with respect to alkenylboranes in good yields.
通过烷炔的氢硼化容易制备的1-烯基硼烷在甲醇中与煤气反应,存在氯化铂和醋酸钠,可以顺利生成相应的α,β-不饱和羧酸酯,并保持与烯基硼烷的构象一致,产率良好。
