An Efficient Synthesis of Imidazolinium Salts Using Vinyl Sulfonium Salts
摘要:
The synthesis of imidazolinium salts from the reaction of formamidines and (2-bromoethyl)diphenylsulfonium triflate is described. A variety of symmetrical and unsymmetrical imidazolinium Inflate salts were synthesized in high yield in short reaction times under mild conditions. Aromatic and aliphatic N-substituents work well. The reaction is proposed to proceed via generation of a vinyl sulfonium salt Intermediate frorr the bromoethylsulfonium triflate.
