Phenyl areneselenosulfonates (4) are very photosensitlve and easrly undergo photodecomposltron via rnltial homolysls of the Se-S bond. In the presence alkenes this facrle photod1ssocratron of t can be used to lnrtlate a free radical chain reactlon (eq 6) that leads to addrtlon of 2 to the alkene to
Two novel polystyrene-supported selenosulfonate reagents have been developed for AIBN-catalyzed addition to acetylenes and have been used for the synthesis of acetylenic sulfones.
The title compounds were synthesized from a readily available steroidal acetylene by a protocol employing selenosulfonation, introduction of the appropriate side chain at C-24 via an alkyl selenocuprate, and reductive desulfonylation. A similar elimination has been observed in the reaction of the s
