General description
Methylenebis(phosphonic dichloride) is an organophosphorus compound that is commonly used in phosphonylation reactions. It is more reactive and the rate of reaction is faster compared to POCl3. This is because the phosphorus center is more electrophilic due to the lack of electron back-donation from the CH2 group.
Application
Methylenebis(phosphonic dichloride) may be used for the following studies:
- Synthesis of mycophenolic methylenebis(phosphonate) derivatives.
- Phosphonylation of nucleosides.
- Preparation of P,P′-partial esters of methylenebisphosphonic acid.
- Synthesis of symmetrical di- and tetra- esters of methylenebisphosphonic acid.

The preparation of partial esters of methylenebisphosphonic acids has been of recent interest due to their potential therapeutic applications. This paper describes a convenient method to prepare symmetrical methylenebis(alkyl hydrogen phosphonates) by the selective cleavage of the corresponding methylenebis(dialkyl phosphonate)

Novel mycophenolic adenine dinucleotide (MAD) analogues have been prepared as potential inhibitors of inosine monophosphate dehydrogenase (IMPDH). MAD analogues resemble nicotinamide adenine dinucleotide binding at the cofactor binding domain of IMPDH; however, they cannot participate in hydride transfer and therefore

A new transformation of methylene-bis(phosphonic dichloride) into tetrathiobisphosphonate derivatives is reported. The reaction of methylene-bis(phosphonic dichloride) with 1,2-ethanedithiol in bromoform in the presence of AlCl(3) formed methylene-bis(1,3,2-dithiaphospholane-2-sulfide), which gave rise to O,O'-diester-methylenediphosphonotetrathioate analogues 1a-k upon reaction with phenols and alkyl
