Abstract

A sterically protected diphosphinidenecyclobutene with the 2,4,6-tri- tert-butylphenyl group was allowed to react with tert-butyllithium and iodine, successively, to give 2,2',3,3'-tetraphosphinidene-1,1'-bicyclobutyl derivative, and the structure was confirmed by X-ray analysis, showing unusual short contact between the C=P moieties at the 2 and 2' positions. A strong through-space interaction between them appears to play an important role in rationalization of the 31P NMR and UV/Vis.
