EXAMINATION OF BY-PRODUCTS FORMED UPON REACTING TRIALKYL PHOSPHITES WITH 2,4-DICHLOROPHENACYLIDENE BROMIDE AS A MECHANISTIC PROBE OF PERKOW REACTION

Besides the expected O,O-dialkyl-O--2-bromovinyl phosphates the formation of their structural analogs devoid of bromine or having two bromine atoms at the terminal position of vinyl group along with α-alkoxy-β-bromo-2,4-dichlorostyrene, α-alkoxy-β,β-dibromo-2,4-dichlorostyrene, and 2,4-dichlorophenacyl bromide was observed in Perkow reactions between trialkyl phosphites and chromatographically pure 2,4-dichlorophenacylidene bromide.The total quantity of side products markedly increases with increasing polarity of solvent.The formation of all the above mentioned compounds can be plausibly explained by assuming an intimate or solvent separated ion-pair as a common intermediate.
