Abstract
Mass spectra of substituted phenyl p-toluenesulfonates were analyzed with the aid of metastable peaks. Three steps in fragmentation were suggested as the main processes for these compounds i.e., the initial S–O bond cleavage giving sulfonylcation, the second desulfonylation and the final loss of acetylene. Effect of substituent on the rate of the decomposition was observed in these three steps. The results are discussed in terms of various internal energies of the initial fragment ions. Apparently, the rates of the initial decomposition depend on the nature of the substituents.This publication has 13 references indexed in Scilit:
