Abstract
The di‐ium dication formed by triflic acid protonation of the cyclic triphosphenium ion derived from 1,4‐bis‐diphenylphosphinobutane, (dppb), and P3(X = Br or Cl) decomposes via an acyclic dication bearing a PHX group; this intermediate is reduced by SnX2 in the presence of HX to yield a dication with a PH2 primary phosphane terminal group, which is comparatively stable. The structure of this species has been unequivocally confirmed by 31P solution‐state NMR spectroscopy. © 2007 Wiley Periodicals, Inc.
