Arylsulphonylcarbenes have been generated in benzene by thermolysis of arylsulphonyldiazomethanes.Contrary to previous findings arylsulphonylcarbenes and to benzene giving the corresponding arylsulphonylcycloheptatrienes.
Some stable substituted cycloheptatrienyl carbanions

The reaction of some 7-substituted cycloheptatrienes with KNH2 in liquid ammonia is described.In several cases stable carbanions are formed.Their NMR spectra are consistent with a non-planar pentadienyl-like structure.A comparison of the 1H-NMR spectra of 10 and 11 shows the paratropic character of the cycloheptatrienyl anions.
