摘要：
The invention relates to a method for producing a) alkenes of formula (II) by the reaction of a) primary alcohols (R1R2CHCH2 - OH) or b) secondary alcohols (R1R2CHCHR3 - OH) or c) tertiary alcohols (R1R2CH - CR3R4OH) with cyclic alkylphosphonic acid anhydrides at a temperature ranging between -100 and +120 °C, whereby R and/or R1 and/or R2 and/or R3 and/or R4 represent H, a linear or branched C1-C12 alkyl group, or a C3-C10 cycloalkyl group, alkenyl group or an aryl group or heteroaryl group. Preferably, a 2,4,6-substituted 1,3,5,2,4,6-trioxatriphosphinane-2,4,6-trioxide of formula (I) is used as the cyclic phosphonic acid anhydride, where R' represents, (independently of one another), allyl, aryl or open-chained or branched C1 to C12 alkyl groups. Optionally the reaction can be carried out in the presence of a tertiary amine base NR53.
