On the Intramolecular Interactions of Si/P in 1,2‐Phenylene Frameworks

On the Intramolecular Interactions of Si/P in 1,2‐Phenylene Frameworks 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.

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.
