Palladium-catalyzed tandem reactions of β-(2-bromophenyl)-α,β-unsaturated carbonyl compounds with 2-hydroxyphenylboronic acid for the synthesis of benzo[c]chromenes are presented. This mild reaction allows formation of onecarbon–carbon bond and one carbon–oxygen bond in one pot.
钯催化β-(2-溴苯基)-α,β-不饱和羰基化合物与2-羟基苯基硼酸的串联反应合成苯并[c]色烯。这种温和的反应允许在一锅中形成一个碳-碳键和一个碳-氧键。
