通过环丁烯酮与炔烃以及缺电子烯烃的开环反应，开发了一种新型铑催化合成取代酚的方法。两个反应都涉及环丁烯酮的 C-C 键断裂，并且 (eta(4)-乙烯基乙烯酮)铑络合物而不是铑环戊酮被认为是关键中间体。 (c) 2007 Elsevier Ltd. 保留所有权利。
A novel rhodium-catalyzed synthesis of substituted phenols by the ring-opening reaction of cyclobutenones with alkynes as well as electron-deficient alkenes has been developed. Both reactions involve C-C bond cleavage of cyclobutenones, and an (eta(4)- vinylketene)rhodium complex rather than a rhodacyclopenterione is considered to be a key intermediate.
