Solution and Flash Vacuum Pyrolyses of β-(3,5-Disubstituted-phenyl)ethanesulfonyl Azides. Sultam, Pyrindine, and Azepine Formation
The solution and flash vacuum pyrolyses of β-(3,5-disubstituted-phenyl)ethanesulfonyl azides are reported.When R = Me, FVP results suggest that the substituents stabilize the intermediate leading to the 3,4-dihydro-2,1-benzothiazepine 2,2-dioxide (6a).A n

Thermolysis of Sulfonyl Azides Bearing Nucleophilic Neighboring Groups. A Search for Anchimeric Assistance
In a search for anchimeric assistance by n- or ?-donor neighboring groups in sulfonyl azide decompositions, 25 sulfonyl azides have been prepared and thermolyzed in 1-chloronaphthalene.First-order rate constants at 135 and 165 deg C were determined by mea
