Chemistry and Pharmacology
The 1,2-azaphosphinine, 9, and the 1,3-diphosphinine, 10, can be isolated from a mixture resulting from the reaction of 1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete, 1, and ethyl isothiocyanate. The reaction of 1 with phenyl isothiocyanate yields the 1,2-azaphosphinine, 16. Mechanisms for the formation of the compounds 9, 10, and 16 are suggested. The properties, the NMR, mass, and IR spectra, and the molecular and crystal structures of 9 and 10 are described and discussed.
