摘要

C, C-Dicyanoketenimines 10a-c were generated by flash vacuum thermolysis of ketene N, S- acetals 9a-c or by thermal or photochemical decomposition of α-azido-β- cyanocinnamonitrile 11. In the latter reaction, 3, 3-dicyano-2-phenyl-1-azirine 12 is also formed. IR spectroscopy of the keteniminines isolated in Ar matrixes or as neat films, NMR spectroscopy of 10c, and theoretical calculations (B3LYP/6-31G*) demonstrate that these ...
