Abstract

Abstract: Full details of the key mechanistic features and the preparative scope of the thermal reactions of cyclopropenone ketals which proceed by the thermal generation and subsequent cycloaddition reactions of x-delocalized singlet vinylcarbenes, three-carbon l, l- /1, 3-dipoles lacking octet stabilization, are described and include, 2, participation in cheletropic [, 2,+, 2,] nonlinear cycloadditions with an observable endo effect suitable for a ...
