✦ Synopsis

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 form 8-phenylselenosulfones (2) The photoaddltion requires much shorter reaction times than the non-photolytlc addltron of 4 to alkenes descrrbed recently.
