โœฆ Synopsis

The generation of sulphene intermediates has attracted considerable attention over the last few years.' Such intermediates have been suggested in the thermolytic* and photolytic3*4 fragmentation of cyclic sulphones. Trapping experiments indicate3 that vinyl sulphenes (2') are involved in the photolysis of thiete sulphone derivatives, e.g. (1). In the absence of methanol, loss of sulphur monoxide occurs. Ph 1 2 Photolysis of 2H-1-benzothiopyran-l,l-dioxide5 (3 in dfchloromethane or methanol with light of 254 nm wavelength gave a mixture of cyclic sulphinate esters (sultines). Indene, 2H-1-benzopyran, and the & sultine (x)6 b.p. 122'/0.1 mn, ~(100 MHz. CsDs),

A~tract~opolymers ofcyclohexene and cyclohexa-l,3-diene with sulphur dioxide have been prepared [poly-l,2-(cyclohexane)sulphone and poly-l,4-(cyclohexa-2-ene)sulphone, respectively], and a study made of their aromatization. It was found that the latter copolymer only could be partially aromatized by
