Synthesis of polyfluoroaromatic magnesium compounds through the exchange reaction

Abstract A convenient synthesis for the preparation of various polyfluoroaromatic magnesium compounds through the magnesium-halogen exchange reaction is described. The reaction between ethylmagnesium bromide and chloride with various bromo- and chloropolyfluoroaromatic compounds provides the polyfluoroaromatic magnesium compounds usually in high yields. Anomalous instability of the (pentafluorophenyl)magnesium chloride is noted.

Synthesis of 2- and 2,5-substituted benzoxazoles and benzothiazoles

Abstract A number of 2- and 2,5-perfluoroalkyl and perfluoroalkylether substituted benzoxazoles and benzothiazoles have been prepared. Their relative hydrolytic stability has been examined. In all cases the benzothiazoles were more stable that the benzoxazoles. Substituents in the 2-position offering steric hindrance improve hydrolytic stability.

Synthesis and reactions of some pentabromophenyl organometallics

Abstract The reactions of pentabromophenylmagnesium bromide (I) with chlorosilanes, benzoyl chloride, sulfur, iodine, and iodotrifluoroethylene are described. The synthesis of a pentabromophenylcopper complex (IX) from the Grignard, and some of its reactions are also reported.
