Allenic phosphonates, readily accessible from 1-alkin-3-ols, the addition products of 1-alkines to aldehydes or ketones, can be transformed to β-ketophosphonates by nucleophilic addition of diethylamine and subsequent hydrolysis of the formed enamines.
烯丙基膦酸酯很容易从1-alkin-3-ols中获得,1-链烷烃与醛或酮的加成产物,可以通过二乙胺的亲核加成和随后形成的烯胺的水解转化为β-酮膦酸酯。
