报道了金属铬催化炔烃的硼氢化反应. 廉价易得的三氯化铬在4,4'-二叔丁基-2,2'-联吡啶配体及单质镁的还原作用下表现出高反应活性, 催化实现了频哪醇硼烷与炔烃加成的硼氢化反应, 为室温条件下制备烯基硼化合物提供了一条有效的合成策略.

关键词: 铬催化, 硼氢化反应

The chromium-catalyzed hydroboration of alkynes under mild conditions was reported. Low-cost chromium(III) chloride combined with 4,4'-di-tert-butyl 2,2'-bipyridine as the ligand and magnesium as the reductant shows high reactivity, which can catalyze and promote the hydroboration of alkynes with pinacolborane, thereby providing a strategy to form borylated olefins at ambient temperature.

Key words: chromium catalysis, hydroboration
