PRACTICAL ASPECTS OF THE CHEMISTRY OF METAPHOSPHATES AND OTHER TRANSIENT DIOXOPHOSPHORANES

Practical laboratory procedures now exist for the generation of organi c derivatives of metaphosphoric acid (KO-PO2), as well as for dioxopho sphoranes (R-PO2). These methods are evaluated in this review. Althoug h these substances are highly reactive and have but a fleeting existen ce, they can nevertheless be employed as reactants in synthetic phosph orus chemistry. The various applications that have been demonstrated i n the literature are also discussed in this review.
