Diazepines. Part 30.1 A Comparison between the Extent of Delocalisation of Electrons in a Vinamidine and its Protonated Form. Crystal and Molecular Structure of Two 2,3-Dihydro-1,4-diazepines
Abstract
An X-ray study of two 2,3-dihydro-1,4-diazepine bases shows that their vinamidine systems are made up of alternate single and double bonds, in contrast to the derived monocations which contain fully delocalised vinamidinium structures.
