The results of the carbanionic reaction between acetonitrile and chlorophosphates depend strongly on the nature of the metallating agent (LiTMP, LDA, LiHMDS). According to the nature of the base, the reaction can be directed towards the formation of either cyanomethylphosphonates 3 or cyanomethylenediphosphonates 5. Electrophilic halogenation of lithiated cyanomethylphosphonate 2a leads to the mono-chloro 17,- ...
