Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
C07F 902
US Classification:
2606065P
Abstract:
Phosphine oxides of the formula ##SPC1## Wherein Ar is a mono- or di-carbocyclic aromatic radical which may be substituted by up to 5 substituents selected from the group consisting of halogen and alkyl of 1 to 3 carbon atoms, Z is halogen or alkyl of 1 to 3 carbon atoms, n is a whole number from 1 to 3, m is a whole number from 0 to 5, and n + m is a whole number from 1 to 6, are prepared by reacting 1. a benzylic halide of the formula ##SPC2## Wherein X is chlorine, bromine or iodine; and Z, n and m are as specified above, 2. a diarylhalophosphine of the formula Ar. sub. 2 PX' wherein Ar is as specified above, and X' is chlorine, bromine or iodine, and 3. an alkali metal hydroxide or an alkaline earth metal hydroxide.
