Abstract

The synthesis and structure of 1-diphenylphosphino-2-(fluorodiphenylsilyl) benzene 1 and 1-diphenylphosphino-2-(difluorophenylsilyl)- benzene 2 are reported. An X-ray crystal structure analysis of 1 shows a weak interaction between the silicon and phosphorus moieties, producing a hypervalent state at the silicon. The hypervalent state of the silicon is also supported by a natural bond orbital calculation. However, despite having a difluorosilyl group, 2 does not show a hypervalent state for the silicon, based on an X-ray crystal structure analysis. © 2012 Wiley Periodicals, Inc.
