ortho-olefinated phenol carbamate, including a ruthenium(II)-catalyzed oxidative olefination of phenol carbamate with acrylates and a rhodium(III)-catalyzedalkynehydroarylation of phenol carbamate with internal alkynes through direct C–H activation, are reported. Both reactions afford substituted alkenes in a highly regio- and stereoselective manner.
可用于获得邻位烯烃化苯酚氨基甲酸酯的两种途径,包括钌 (II) 催化的苯酚氨基甲酸酯与丙烯酸酯的氧化烯烃化和铑 (III) 催化的苯酚氨基甲酸酯与内部炔烃通过直接 C-H 的炔烃加氢芳基化激活,报告。这两个反应都以高度区域和立体选择性的方式提供取代的烯烃。
