Synthesis and structures of new conformationally rigid 1-aza-1,3-dienes of the acenaphthene series

摘要

The Wittig reaction of 1-tert-butyliminoacenaphthen-2-one with benzylidenetriphenyl-phosphoranes produces new 1-aza-1,3-dienes of the acenaphthene series,which can bind butyllithium to the C=C bond of the enimine fragment C=C-C=N.
