The first generalpalladium-catalyzedcarbonylative vinylation of aryl halides with olefins in the presence of CO has been developed. Applying a catalyst system consisting of [(cinnamyl)PdCl](2) and bulky imidazolyl-phosphine ligand L1 allows for the efficient and selective synthesis of α,β-unsaturated ketones under mild reaction conditions. Starting from easily available aryl halides and olefins,
在 CO 存在下,第一个通用钯催化的芳基卤化物与烯烃的羰基化乙烯基化已经被开发出来。应用由 [(肉桂基)PdCl](2) 和庞大的咪唑基膦配体 L1 组成的催化剂体系,可以在温和的反应条件下高效和选择性地合成 α,β-不饱和酮。从容易获得的芳基卤化物和烯烃开始,可以以简单的方式制备通用的结构单元。证明了这种新协议的通用性和功能组耐受性。
Continuous-flow hydration–condensation reaction: Synthesis of α,β-unsaturated ketones from alkynes and aldehydes by using a heterogeneous solid acid catalyst
A simple, practical and efficient continuous-flow hydration-condensation protocol was developed for the synthesis of alpha,beta-unsaturated ketones starting from alkynes and aldehydes by employing a heterogeneouscatalyst in a flow microwave. The procedure presents a straightforward and convenient access to valuable differently substituted chalcones and can be applied on multigram scale.
The trans isomers of both poly(4′-vinylbenzalacetophenone) and a model compound, 4′-ethylbenzalacetophenone, readily form the corresponding cis isomers on exposure of their solutions to ultraviolet radiation. The cis isomers can be isolated and, in the case of the nonpolymeric material, the cis form reverts readily to the trans form upon addition of a trace of hydrogen chloride. The polymer, however
