The mechanism of photodecomposition of aryl sulfones has been investigated by using both steady-state and time-resolved techniques. Direct evidence for radical and triplet-state intermediates is provided. A correlation is found between the dynamics of reaction of the intermediate triplet states with the stabilities of the intermediate radicals.

Dibromotetrachloroethane (C2Br2Cl4) is demonstrated as a halogenating reagent for the one-pot conversion of sulfones to alkenes by way of the Ramberg–Bäcklundrearrangement. Dibromotetrachloroethane successfully replaces known ozone depleting agents CCl4, CBr2F2 and C2Br2F4. A formal synthesis of E-resveratrol is demonstrated using C2Br2Cl4.
已证明二溴四氯乙烷(C 2 Br 2 Cl 4)作为卤化试剂,可通过Ramberg-Bäcklund重排将砜一锅转化为烯烃。二溴四氯乙烷成功替代了已知的臭氧消耗剂CCl 4,CBr 2 F 2和C 2 Br 2 F 4。使用C 2 Br 2 Cl 4证明了E-白藜芦醇的正式合成。
