Article abstract of DOI:10.1016/0022-328X(92)83440-S

Single crystal X-ray diffraction measurements on the adduct obtained from neopentyl diphenylphosphinite and phenacyl bromide show this Michaelis-Arbuzov intermediate to be a phosphonium compound, with a tetrahedral arrangement of bonds around phosphorus a
