Abstract (en)
[origin: WO2005102978A1] The invention relates to a method for the production of a.) aldehydes of formula (II): R<1_> CHO and b.) aldehydes of formula (III): R<1_> C(O) <_> R<2> by reacting a.) primary alcohols (R<1>CH2-OH) or b.) secondary alcohols (R<1>-CH(OH)-R<2>) with cyclic phosphonic acid anhydrides in the presence of dialkyl-, diaryl- and/or alkyl-aryl sulphonic oxides at a temperature in the region of between -100 to + 120 DEG C, whereby R<1> and/or R<2> represent H, a substituted linear or branched C1-C12-alkyl radical, a substituted C3-C10 cycloalkyl-, alkenyl-, aryl- or heteroaryl radical. A cyclic phosphonic acid anhydride is used, preferably, as a 2,4,6-substituted 1,3,5,2,4,6-trioxatriphosphinane of formula (I), wherein R' independently represents allyl, aryl or open-chained or branched C1 - C12-alkyl-radicals. Optionally, the reaction can be carried out in the presence of a tertiary amine base NR<5>3.
