The rhodium(I)-catalyzed reaction of alkynes with arylboronic acids in the presence of formaldehyde resulted in a carbon monoxide gas-free carbonylative arylation to yield α,β-enones. The simultaneous loading of phosphine-ligated and phosphine-free rhodium(I) complexes is required for efficient catalysis, which catalyze the abstraction of a carbonyl moiety from formaldehyde (decarbonylation) and its
在甲醛存在下,炔烃与芳基硼酸的铑 (I) 催化反应导致无一氧化碳气体的羰基化芳基化反应生成 α,β-烯酮。高效催化需要同时加载连接膦和不含膦的铑 (I) 配合物,分别催化从甲醛中提取羰基部分(脱羰),然后将其引入底物(羰基化)。
