Styrene and cinnamic acid derivatives yield correspondingly substituted benzaldehydes
when oxidized by permanganate under heterogeneous conditions. Reaction of terminal
aliphatic alkenes under similar conditions gives discouragingly low yields; however,
ketones and ketols are obtained in very good yields from the oxidation of 2,2-disubstituted
and trisubstituted alkenes, respectively. Alumina and Amberlite IR-120 can be used
as solid supports in these reactions with equally good results.
