PHOSPHOR- UND SCHWEFELSUBSTITUIERTE ALLENE IN DER SYNTHESE I : EINFACHE SYNTHESE VON β-KETOPHOSPHONATEN AUS 1-ALKIN-3-OLEN

Altenbach, Hans-Josef,Korff, Rainer

, p. 5175 - 5178 (2007/10/02)

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.
