    • The invention relates to a method for the production of a.) aldehydes of formula (II): R1—CHO and b.) aldehydes of formula (III): R1—C(O)—R2 by reacting a.) primary alcohols (R1CH2—OH) or b.) secondary alcohols (R1—CH(OH)—R2) 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° C., whereby R1 and/or R2 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 NR53
