A general approach to obtain pyrophosphonates is achieved by reacting arylphosphonic acids with AgNO(3) in CH(3)CN under solvothermal conditions; the process is coupled with the C-C bond cleavage of acetonitrile and the formation of novel complexes Ag(n)(RPO(2)(O)O(2)PR)(m); the mechanism of the process is proposed.
通过在溶剂热条件下使芳基膦酸与硝酸银在乙腈中反应，实现了一种获得焦膦酸盐的通用方法；该过程伴随着乙腈的C-C键断裂以及新型配合物Ag(n)(RPO(2)(O)O(2)PR)(m)的形成；并提出了该过程的机理。
