Diphosphenes

Diphosphene is a type of organophosphorus compound that has a phosphorus–phosphorus double bond, denoted by R-P=P-R'. These compounds are not common, but their properties have theoretical importance.

Normally, compounds with the empirical formula RP exist as rings.  However, like other multiple bonds between heavy main-group elements, P=P double bonds can be stabilized by large steric hindrance.[1] In general, diphosphenes react like alkenes.
