摘要

Abstract The reactions of a series of α-substituted p-nitrobenzyl chlorides, p-NO 2 C 6 H 4 CH (Cl) R (R= Me, Et, Pr t, Bu t), with the lithium salt of 2-nitropropane in dimethyl sulphoxide and dimethylformamide have been studied. When R= Me or Et, competing S RN 1 and SN 2 processes take place, giving C-and O-alkylated products respectively. In the more sterically hindered cases where R= Pr i or Bu t, the only reaction taking place has been shown to be ...
