Novel Synthesis and Crystal Structure of Benzyloxy-Bis-PentafluorophenylboraneAuthor(s): Hailey Beal, Lev Zakharov, Eric R Abbey
The title compound, C19H7BF10O, was formed by the reaction of pentafluorophenylmagnesium bromide with in situ generated benzyldichloroborane, followed by exposure to molecular oxygen, resulting in an oxygen insertion reaction into the C-B bond. The molecule features a trigonal planar boron, with containing a B-O bond with significant double bond character. A weak hydrogen bond between H7 and O is observed, resulting in an S (5) ring. In the structure, weak π-π interactions between the phenyl and pentafluorophenyl rings form chains along the  axis.
