continuous flow alcoholysis of dialkyl H-phosphonates by aliphatic alcohols in the absence of a catalyst was elaborated using a microwave (MW) reactor equipped with a flow cell. By the precise control of the reaction conditions, the synthesis could be fine-tuned towards dialkyl H-phosphonates with two different and with two identical alkyl groups. In contrast to the "traditional" batch alcoholysis, flow approaches

diesters of phosphorousacid were prepared in good yields by the reaction of primary or secondary alcohols, such as methanol, ethanol, and s-butanol, or of phenols, such as phenol, p-chlo-rophenol and p-cresol, with ethyl N-phenylimino phosphite and p-toluenesulfonic acid monohy-drate. Similarly, when carboxylic acids, such as acetic acid, benzoic acid, p-chlorobenzoic acid and trichloroacetic acid, were
