Abstract
The reaction of phosphinoselenoic chlorides 1 with various organolithium and magnesium reagents was studied. Sequential reaction of phosphinoselenoic chlorides 1 with organolithium and magnesium reagents and elemental selenium gave two types of products, phosphine selenides 2 and phosphinodiselenoic acid esters 3. The esters 3 appeared to be formed via the selenophilic reaction of organolithium and magnesium reagents with the chlorides 1. Molecular orbital calculations were carried out for model compounds H2P(E)Cl (E = O, S and Se) to determine their electronic structures. © 2005 Wiley Periodicals, Inc.
