Novel (3+2) Photocycloadditions with 3-(1-Alkynyl)cyclohexenones and Tetramethylethylene

Irradiation of 3-alkynylcyclohexenones (3) with tetramethylethylene gives rise to novel (3+2) cycloadducts that can be explained mechanistically in terms of closure of an initial biradical (6) to a vinyl carbene (7), followed by stabilization of the carbene.

Novel [3 + 2] photocycloadditions of 3-(1-alkynyl)-2-cycloalken-1-ones with alkenes

Photochemical cycloaddition of 3-alkynylcycloalkenones 3a,b,c and 4 with tetramethylethylene (8) at ～40°C leads to mixtures of 1:1 adducts that arise largely from 1,5 closure of the biradical intermediate (eq 1), providing examples of a novel [3 + 2] cycl
