Abstract

Depending on the ratio of reactants, reaction of (PPh)₅ (1) with grey selenium gives (PhPSe₂)₂ (2), (PhP)₃Se₂ (3), (PhP)₄Se (4), and (PhP)₃Se₃ (5). The compounds have been characterized by multielement NMR, mass spectrometry, microanalyses, and, in the case of 4, X‐ray crystallography. 4 consists of a puckered 5‐membered ring with all four phenyl substituents axial; the average P–P and P–Se bond lengths are 2.194 and 2.271 Å respectively.
