| Abstract: | Active halide containing electron withdrawing group (EWG) α-to halogen readily reacts with 4-dimethylaminopyridine (DMAP) to give stable salt of pyridinium halide (1-6). The reaction between 1-phenacyl-4-dimethylaminopyridinium halide(s) (1 and 2) and aq. NaOH instantaneously generates 4-dimethylaminopyridinium-1-(2'-hydroxy-2'-phenyl)vinylide 7 as brownish yellow stable crystalline solid which is reported for the first time. Whereas, the other compounds 3-6 do not generate such type of ylide under identical experimental conditions. |
