Synthesis of S-aryl thioesters via palladium-catalyzed thiocarbonylation of aryl iodides and aryl sulfonyl hydrazides
文献情報
Yeojin Kim, Kwang Ho Song, Sunwoo Lee
Aryl iodides and aryl sulfonyl hydrazides were reacted with carbon monoxide in the presence of DBU and a palladium catalyst to provide optimal yields of S-aryl thioesters. Aryl sulfonyl hydrazides served as aryl thiol surrogates. Optimal results were obtained when the reaction was carried out with Pd(dba)2/dppb in toluene at 80 °C for 12 h. The methodology exhibits superior functional group tolerance, being compatible with moieties like fluoride, chloride, bromide, ester, ketone, cyanide and nitro.
