Carbonyl‐olefin metathesis and carbonyl‐alkyne metathesis represent established reactivity modes between carbonyls, alkenes, and alkynes under Lewis and Brønsted acid catalysis. Recently, an interrupted carbonyl‐olefin metathesis reaction has been reported that results in tetrahydrofluorenes via a distinct fragmentation of the reactive intermediate. We herein report the development of an analogous transformation interrupting the carbonyl‐alkyne metathesis reaction path resulting in dihydrofluorene products relying on Lewis acidic superelectrophiles as active catalytic species.

羰基-炔烃复分解中断

羰基-烯烃复分解和羰基-炔烃复分解表示在路易斯和布朗斯台德酸催化下羰基，烯烃和炔烃之间已建立的反应模式。最近，据报道羰基-烯烃复分解反应中断，通过反应性中间体的明显断裂产生四氢芴。我们在此报告了类似的转化过程的发展，该转化过程中断了羰基-炔烃的复分解反应路径，导致依赖于路易斯酸性超亲电子试剂作为活性催化物质的二氢芴产品。
