Abstract

The first carbonyl halide zwitterionic complexes have been synthesized and are of the type cis- (OC)₄XWPPh₂(CH₂)nPPh₂R in which X is Cl, Br, or I, n is 1 or 2, and R is an alkyl group. The complexes were prepared by the reaction […]. The temperature of the reaction must be carefully controlled since the decomposition point of the product is only 10°C higher than that of the reactant.

The zwitterionic complexes are sensitive to light in solution but are insensitive to light in the solid state. Unlike carbonyl halide complexes of the type (R₄N)(XW(CO)₅), the zwitterionic complexes are not as sensitive.

The zwitterionic complexes were characterized by infrared, ultraviolet/visible and proton NMR spectrascopy and by elemental analyses.
