Cyclic structure of n-methyl- 2-aminobenzoyl- and 2-mercapto- benzoylhydrazones of fatty- aromatic aldehydes
摘要:
It has been shown by H-1 NMR spectroscopic methods that the previously unknown N-methyl-2-aminobenzoyl- and 2-mercaptobenzoylhydrazones of phenylacetic and 3-phenylpropionic aldehydes have cyclic benzo-1,2,4-triazepine and benzo-1,3,4-thiadiazepine structures respectively.
