Palladium-catalysed carbonyl allylation by 2-methylenepropane-1,3-diol
Abstract
2-Methylenepropane-1,3-diol first allylates an aldehyde exclusively at the allylic alcohol moiety at room temperature and then, at 50 °C, allylates another aldehyde also at the allylic alcohol moiety, in the presence of a catalytic amount of PdCl2(PhCN)2 with tin(II) chloride.
