2H-Azirines from a Concerted Addition of Alkylcarbenes to Nitrile Groups
摘要:
Photolysis of aziadamantanos in the presence of fumoronitrile (FN) unexpectedly afforded conjugated 2H-azirines resulting from addition of the carbene to the CN triple bond. This represents the first example of a direct azirine formation starting from an alkylcarbene for which a concerted pathway is postulated. The novel outcome if the reaction is favored by the prior formation of a carbene-alkene complex, a type of adduct that only recently has been described.
