Abstract
When cyclic a, ~UllSaturated carbonyl compounds were irradiated by ultraviolet from a high pressure mercury vapour lamp at 25 ·C,.in alcohols in the presence of titanium chloride, a coupling reaction between the carbonyl carbon atom and the a-carbon atom of the alcohol took place, producing dihydrofurans, monomethylether, acetals oc aldehides, but in the case of a-methyl substituted enone it resulted in diol monomethylether due the two times occuring methanol substitution.
