Abstract
The ability for transesterification of alkoxyphosphoryl and alkoxy-carbonyl groups has been investigated, using dialkyl esters of 2,3-dialkoxycarbonyl-propanephosphonic acid as a model. Their interaction with ethylene glycol, diethylene glycol, and n-octanol in the presence of a catalyst (MnAc2 or Na glycolate) has been studied using GC, GPC, and 1H-NMR. It has been established that the transesterification of the alkoxy groups at the phosphorus atom is difficult, while the alkoxy groups at the carbonyl carbon atom are nearly always 100% trans-esterified.
