Thermal decomposition of the 2H-azaphosphirene complex 1 in the presence of kinetically stabilised phosphalkynes 2a,b yields the 1H-diphosphirene complex 4a and the 1,2-dihydro-1,2,3-triphosphete complex 5; for the latter the overall reaction may be described as an insertion of a phosphanediyl complex into a ring bond of a transiently formed 1H-diphosphirene complex, with loss of one pentacarbonyltungsten moiety.
