The O-silylated dienolates of unsaturated ketones and esters can be alkylated using zinc bromide catalysis to give predominantly the y-alkylated carbonyl compounds. The substitution pattern of the substrate (11, favours, in certain cases, very high or complete y-selectivity.
When cuprous bromide reacts with an excess of ethylmagnesium bromide in ethyl or c-butyl ether, a copper-containing red solution is formed that markedly catalyzes the reaction of ethyl bromide with ethylmagnesium bromide to give a mixture of ethane and ethylene, 2 usually in the ratio of 1.3 or less
