| Description |
295-298
Active halide containing electron withdrawing group (EWG) α-to halogen readily reacts with 4-dimethylaminopyridine (DMAP) to give stable salt of pyridinium halide (<b>1-6</b>). The reaction between 1-phenacyl-4-dimethylaminopyridinium halide(s) (<b>1</b> and <b>2</b>) and aq. NaOH instantaneously generates 4-dimethylaminopyridinium-1-(2'-hydroxy-2'-phenyl)vinylide <b>7</b> as brownish yellow stable crystalline solid which is reported for the first time. Whereas, the other compounds <b>3-6</b> do not generate such type of ylide under identical experimental conditions. |
