CHEMOSELECTIVE ETHYLENE ACETALIZATION OF α,β-UNSATURATED vis-a-vis SATURATED CARBONYL GROUPS

Article abstract of DOI:10.1016/0040-4039(84)80004-0

The difficulties which in the past have precluded controlled acetalization of an α,β-unsaturated ketone functionality in the presence of a saturated carbonyl group can be overcome simply by making recourse to 2,4,6-collidinium p-toluenesulfonate as catalyst.
