Abstract

The solid state structures of a number of ortho-substituted arylboronic acids, ortho- bromophenyl, ortho-phenylphenyl, pentamethylphenyl, and 10-bromo-9-anthryl, were determined by X-ray diffraction techniques. All boronic acids investigated form dimers in the solid state, but the interconnection of dimers to ribbons differs from that of the parent phenylboronic acid. Pentamethylphenylboronic acid only uses onehydrogen bond but an ...
