摘要:
The nudeophilic trifluoromethylthiolation of benzyl bromides using (bpy)Cu(SCF3) gave the desired products of benzyl trifluoromethyl sulfides in good to excellent yields. A diverse set of important functional groups including cyano, nitro, ester, alkoxy, halide, and heterocyclic groups can be well tolerated in the protocol. (C) 2013 Elsevier Ltd. All rights reserved.

Directtrifluoromethylthiolation and trifluoromethylselenolation of alcohols with the new CS(Se)CF3 reagent based on imidazole skeleton has been realized. The reaction proceeds smoothly at room temperature under transition-metal-free conditions and affords the corresponding trifluoromethylthiolated and trifluoromethylselenolated products in good yields. Advantages of the method include mildness, good

S‐Containing Stereocenters Catalysed by Chiral Quaternary Phosphonium Salts
A series of benzyl trifluoromethyl sulphides bearing a nitro group were utilized as CF3S‐containing buildingblocks to construct chiral CF3S‐containing molecules via enantioselective vinylogous Mannich‐type reactions. In such reactions, high yields and enantioselectivities were obtained using chiral quaternary phosphonium salts derived from amino acids. Moreover, a chiral cyclic urea bearing the CF3S
