| Abstract: | ![]()
Many 1,3‐azoles and thiophenes are directly cyclopropylated in the presence of a simple palladium catalyst. The relative configuration on the three‐membered rings is retained in the products. Thus, the cyclopropyl–halide bond undergoes concerted oxidative addition to palladium(0) and cyclopropyl radicals are not involved in the productive pathway. |
