Description / Table of Contents:
The peak at [M - 1] in the fragmentation pattern of N,N-dimethylbenzamide is formed by the loss of a hydrogen not from one of the methyl groups, but from the aromatic ring. This is proved by the fragmentation pattern of N-trideuteriomethyl N-methyl-, N,N-di(trideuterio)methyl and N,N-dimethyl 2,4,6-trideuterio benzamide. The preparation of these labelled compounds is described.
Notes:
Le pic à [M - 1] dans le spectre de masse de al N,N-diméthybenzamide provient de la prete d'un hydrogène du noyau aromatique et nonpas d'un des groupes méthyles. La preuve en est faite en comparant les spectres de al N-trideutériométhyl N-méthyl-, N,N-di(trideutério)méthyl- et N,N-diméthyl 2,4,6-trideutério bezamide. On décrit la préparation de ces produits.
