Abstract

The electron impact induced fragmentations of m- and p-substituted phenylacetamides and N,N-dimethyl-phenylacetamides 1-14 were investigated and compared with the o-analogues. A l l m- and p-substituted amides yield molecular ions with high relative intensities which do not lose their meta- and para-substituents. Loss of HNCO from M + * is dominant in the prim, amides, whilst for the tert. ...
