Gas phase elimination of methyl group from acetophenones within the range of 10−11 to 10−6 second

Abstract

The field ionization of acetophenone,p-methyl andp-chloroacetophenones on a 5 μm activated wire yields an abundant peak at parent minus CH3 group. Variations of the reaction rate as a function of the decomposition times of the elimination reaction in the range 10−11–10−6 sec are studied. Remarkable changes in the reaction rate according to the type of the substituent are noticed.
