reductive benzylation reactions with aryl aldehydes. By using a H3PO3/I2 combination, various aromaticaldehydes underwent iodination reactions and Friedel–Crafts typereactions with arenes via benzyl iodide intermediates, readily producing benzyl iodides and diarylmethanes in good yields. Intramolecular cyclization reactions also took place, giving the corresponding cyclic compounds. This new strategy features
在与芳基醛的苄基还原反应中,H 3 PO 3首次被用作还原剂和促进剂。通过使用H 3 PO 3 / I 2组合,各种芳族醛经过苄基碘中间体与芳烃进行碘化反应和Friedel-Crafts型反应,可轻松以高收率生产苄基碘和二芳基甲烷。分子内环化反应也发生,得到相应的环状化合物。这种新策略具有易于处理,低成本和无金属的条件。

The electron-transfer-induced photocyclization reactions of a series of N- and C-silylmethallyl-substituted iminium and 1-benzyl-1-pyrrolinium salts have been investigated in order to gain information about their mechanistic course and to probe their synthetic potential. The results obtained from these studies demonstrate that diradical cation intermediates formed in these processes can be transformed
