o-Quinonoid Compounds. Part 17. Evidence for exo-Selectivity in the 1,5-Sigmatropy of Acyl and Vinyl Groups

Arguments and experiments are presented which suggest that in the 1,5-sigmatropic shift of acyl groups in 1-acylindenes the acyl group prefers to adopt a transition state (t.s.) arrangement with the acyl-oxygen directed away from the indene ring (3-exo) r
