Decomposition organophosphorus compounds

Ultrasonic extraction, also known as sonication, uses ultrasonic vibration to ensure intimate contact between the sample and the solvent. Sonication is relatively fast, but the extraction efficiency is not as high as some of the other techniques. Also, it has been reported that ultrasonic irradiation may lead to the decomposition of some organophosphorus compounds [12]. 

This review summarizes experimental and theoretical studies which are used to develop theoretical models that explain and predict how clay minerals and metal oxides can affect the adsorption and decomposition of selected organophosphorus compounds. The results can contribute to a better knowledge of the impact of such processes on existing remedial technologies and in the development of new removal and decomposition techniques.

For sometime, phosphinidines, monovalent organophosphorus species with the general formulation (R-P), have been postulated as reactive intermediates in the thermal and photochemical decomposition of several types of stable organophosphorus compounds. While not isolated as stable molecules, these monovalent species can be inferred on the basis of the isolation of products whose structures can be derived rationally from the postulation of such species, as well as on the mass spectra of the transient species themselves. We may view phosphinidines as the phosphorus analogues of nitrenes (R-N), highly reactive monovalent nitrogen species formed as transient intermediates in the thermal decomposition of azides and in the a-elimination reaction of A-tosylates.
