Abstract
Preparation of a novel conjugated tetraorganoborate is
presented
in a facile two-step procedure. Successful utilization as a halide
abstraction reagent is demonstrated in a metathesis reaction with
the platinum(II) boryl complex [(Cy<sub>3</sub>P)<sub>2</sub>Pt(Br)(BC<sub>4</sub>Ph<sub>4</sub>)], which was obtained by oxidative addition
of 1-bromo-2,3,4,5-tetraphenylborole to a platinum(0) species. The
novel compounds were investigated by means of spectroscopic and X-ray
diffraction techniques
