Trifluoromethyl-substituted dehydrodiazepines and cyanopyrroles from azido-/tetrazolo-pyridines
Abstract
1,2-Didehydro-1,3-diazepines 4D, 5D, 4,6D and 5,6D are identified as unique products of both photolysis and thermolysis of azido-/tetrazolo-pyridines; the ultimate thermolysis products are trifluoromethylpyrrolecarbonitriles (7–9, 11–13 and 16–18).
