Abstract

ZHANG, Xiang-Zhu; MA, Jing-Ya  and  WU, Ming-shu. A convenient and direct route to 1,2-dichlorovinylphosphine oxides via copper-catalyzed addition of H-phosphine oxides to 1,2-dichloroethyne. S.Afr.j.chem. (Online) [online]. 2012, vol.65, pp.228-230. ISSN 1996-840X.

An efficient, convenient and inexpensive CuI-catalyzed method for the synthesis of 1,2-dichlorovinylphosphine oxides from substituted phosphites, diphenylphosphine oxide and 1,2-dichloroethyne has been developed in moderate-good yields, and the reactions provided mainly regioselective anti addition products.

Keywords : Copper-catalyzed addition reaction; 1,2-dichlorovinylphosphine oxides.
