Acylstannanes were found to add to such alpha,beta-unsaturated carbonyl compounds as enones or ynoates in the presence of a nicel 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.
发现在锡基或钯催化剂存在下,乙酰锡烷酮会添加到烯类或壬酸酯类的α,β-不饱和羰基化合物中,从而生成2-stannyl-4-oxoalk-2-enoates或1,4-二酮,而三个酰基stannanes,烯酮和醛之间的组分偶联提供了2-羟甲基1,4-二酮。
