Phenylmagnesium Bromide

The reaction of organolithium compounds with 1-substituted 2,4,6-triphenylpyridinium perchlorates Ia-Ic produces mixtures of 1,4-dihydropyridines IIa-IIe and 1,2-dihydropyridines IIIa-IIIe. Analogous reactions of phenylmagnesium bromide with compounds Ia-Ic proceed with very low conversions (less than 1%). Photochromism in visible range is observed only with the compounds II which have two aromatic substituents at 4-position, whereas compounds III and IId show no visible photochromism. The molecular spectra of the compounds newly prepared are discussed.

A simplified technique was developed for carbonation of Grignard reagents or organolithium compounds, with C14O2 generated from barium carbonate. 3,4-(Dibenzyloxy)-bromobenzene was treated with n-butyl lithium in ether and then with C14O2 to give 3,4-(dibenzyloxy)-benzoic acid-carboxyl-C14. The yield was 74% based on barium carbonate. 2,6-Dichlorobenzoic acid-carboxyl-C14 (yield 77%) and 3,5-dichlorobenzoic acid-carboxyl-C14 (yield 76%) were prepared from the corresponding dichlorobromobenzenes by a similar sequence of reactions. Attempts to synthesize 2,4- and 2,5-dichlorobenzoic acids by this route gave poor yields of unidentified acids, from which the expected products could not be isolated.
