The oxa-di-π-methane rearrangement of β,γ-unsaturated ketones induced by the external heavy atom cation effect within a zeolite
Abstract
Photolyses of β,γ-unsaturated ketones 1 and 2 included in MY zeolites gave the oxa-di-π-methane products, which are believed to originate from the triplet state caused by heavy atom cations present within the supercage.
