Abstract

Acylstannanes were found to add to such α, β-unsaturated carbonyl compounds as enones or ynoates in the presence of a nickel or palladium catalyst to give 2-stannyl-4-oxoalk-2- enoates or 1, 4-diketones, whereas the three component coupling between acylstannanes, enones and aldehydes provided 2-hydroxymethyl 1, 4-diketones.
