peri-Naphthotriazines and related compounds. Part II. Some acenaphthylene derivatives; their preparation and properties
Abstract
The preparation and properties of some members of a new group of heterocycles derived from acenaphthylene (acenaphtho[5,6-de]triazines etc.) are described. Their electronic structure is compared with that of the non-benzenoid aromatic hydrocarbon cyclohept[fg]acenaphthylene (acepleiadylene). An attempt to generate 5,6-dehydroacenaphthylene is recorded.
