Abstract

Abstract: The hydrolysis of Ph (LG) C= CPh (N02)(4-M, LG= CI, I, SEt, OMe) in basic solution yields the anion of 1, 2-diphenyl-2-nitroethanone, PhC (= O) C (= NO,-) Ph (83, by the addition-elimination mechanism of nucleophilic vinylic substitution (Scheme I), while the reaction of base with Ph (SCH2CH20H) C= CPh (N02)(4-SCH2CH20H) leads to a cyclic intermediate (T) by intramolecular nucleophilic attack by the ionized OH group (eq 6). The ...
