Popis: A convenient and versatile method was developed for the preparation of 1,2-bisphosphorylethanes. Thus, in the presence of a catalytic amount of trimethylphosphine, a variety of >P(O)H compounds efficiently add to vinylphosphoryl compounds to produce the corresponding 1,2-bisphosphorylethanes in high yields. In most cases, the trimethylphosphine catalyst was simply removed under vacuum leaving spectroscopically pure adducts. The present method provided a halogen and metal-free clean process for the preparation of 1,2-bisphosphorylethanes.
