New approaches to the synthesis of diphosphine dioxides and hypophosphoric acid esters

An union >P-O- has been applied as an efficient synthetic precursor of four coordination compounds of the R2P(O)-(O)PR 2 type, namely diphosphine dioxides (R = alkyl, aryl) as well as hypophosphoric acid esters (R = alkoxy, aryloxy), in a one-pot reaction. Furthermore, there were elaborated some mechanistic aspects of the origin of the >P(O)-O-(O)PP-O- and >P(O)X (X= Cl, Br) electrophiles. Attention is focused on the synthesis of the >P(O)-(O)P compounds.
