KF/Al(2)O(3) was found to be an efficient base for the reaction of imines with chloroform in acetonitrile to give gem-dichloroaziridines 2 in moderate to high yields. The KF/Al(2)O(3)-promoted dichloroaziridination can be carried out with simple workup, tolerates a variety of functional groups present in the imines, and proceeds smoothly with a smaller(More)
A novel synthesis of unsymmetrical aryl sulfides, which requires no transition metal catalyst and no oxidant, was developed. This base-promoted cross-coupling reaction proceeded using arylhydrazines and 1 equiv amount of disulfides under inert gas conditions to afford the unsymmetrical aryl sulfides in good yields.
A novel convenient method for the generation of thiocarbonyl ylides from readily accessible starting materials and the first synthetic application of in situ generated ylides in the synthesis of silyl enol and dienol ethers, accompanied by C-C bond formation, is described. Under completely neutral conditions without any catalyst or additive, thermal(More)
