Abstract

A >PO^−^ (1) type of anion has been used as an efficient synthetic precursor of four‐coordinated compounds: R~2~P(O)Hg(O)PR~2~ (5) and R~2~P(O)HgBz (3) (R = alkoxy, alkyl, aryl). They were obtained in good yield. Bis(t‐butyl‐phenylphosphinito‐P)mercury (meso and rac) (5c,d) selectively decomposed into 1,2‐di‐t‐butyl‐1,2‐diphenyldiphosphane 1,2‐dioxide (meso and rac) (6c,d). Furthermore, some mechanistic aspects of the synthesis of mentioned compounds are elaborated.© 2008 Wiley Periodicals, Inc.
