Abstract

5 iiience the cycloelimination reactions are formulated mechanistically in a concerted fashion, although intermediates have not been excluded and in fact may be involved in several~ ases.~, S On the basis of the reactions cited above and related examples, 7JO it was felt that suitably substituted cyclic sulfites such as 7a or carbonates 7b also should undergo [5+ 2+ 2+ 11 photocycloeliminations to give arylcarbenes such as 8 as depicted ...
