Abstract

Masaaki Yoshifuji,* Tadao Ishizuka, Yoon Jung Choi, and Naoki Inamoto Department of Chemistry, Faculty of Science, The University of Tokyo, Hongo, Tokyo 113, Japan ... SUMMARY Diphenylphosphinothioyl compounds were ortho-lithiated and alkyldiphen- yl phosphine sulfides were a-lithiated and the resulting lithio compounds react- ed to give the corresponding o- and a-substituted products. _ ... Very recently Dashan and Trippett' reported the ...
