The sydnone ring as an ortho-director of lithiation. Dilithiation of 3-phenylsydnone and trapping by electrophiles

Turnbull, Kenneth,Krein, Douglas M.

, p. 1165 - 1168 (1997)

Readily available 3-phenylsydnone (3) reacts with n-butyllithium/TMEDA to form the dilithio species 4 which can be trapped with suitable electrophiles. This represents the first use of a mesoionic ring system for directed lithiation.
