Halide derivatives react with an excess of triethyl phosphite under microwave irradiation. In a mono-mode reactor, the reaction is complete within 10 min. Excesses of phosphites and alkyl halides are evaporated under vacuum. The mixture is hydrolyzed by a hydrobromic acid solution during 10 min under microwave irradiation, and the obtained diphosphonic acid is crystallized in water. ... We have used α,ω-dibromoalkanes for the preparation of alkane-α,ω- ...
