Abstract:

In the past few decades, much attention has been focused on palladium-catalyzed carbonylative reactions^[1,2], which is a simple method to synthesize some complicated compounds^[3,4]. This kind of reactions, however, can be carried out only when the substrates are arylhalide, heteroaryl halide, alkene halide,aryltrifluoromethyl-sulfonate and hypervalent iodonium salt^[5] etc. Herein, we report a palladium-catalyzed carbonylative reaction between 3,7-bis(N,N-dimethylamino)-10H-dibenz[b,e] iodinium iodide(1)^[6] with alcohols (2) at ambient temperature as shown in scheme.
