REACTIONS OF CHLOROMETHYL PHENYL SULFONE CARBANION WITH NITROBENZOPHENONES. THE VICARIOUS SUBSTITUTION OF HYDROGEN<i>Versus</i>THE DARZENS CONDENSATION
Carbanion of chloromethyl phenylsulfone replaces hydrogen atoms o′- and p- to the nitro group in o-nitrobenzophenone, whereas with p-nitrobenzophenone it enters the Darzens condensation followed by rearrangement and decarbonylation. Reaction course with m-nitrobenzophenone depends on the conditions (base concetration). When an excess of a base is present the vicarious substitution of hydrogen takes
