Substituted thioureidomethylenebisphosphonic acids react with haloketones to form thiazoles. The cyclization direction is predictably controlled by the size of the substituent. The NMR spectra of the resulting isomeric tetrazoles have well-defined di

The rate and pathway depends in a complicated manner of the cyclization reaction of phenylthioureidomethylenebisphosphonic acid with bromoacetone on the pH of the reaction medium. The dependence is explained in terms of formation of an intramolecular

Derivatives of aminomethylenebisphosphonic acids constitute a class of promising herbicides. Replacement of the amino group by hydroxyl, ureido, thioureido, or imino moieties leads to compounds of significant herbicidal properties. This indicates tha
