Abstract
In the reaction of phenylisocyanate, 1, with 1,3-dimethylurea, 2, and 1,3-diphenylurea, 4, 1,3-dimethyl-5-phenyl biuret, 3, and 1,3,5-triphenylbiuret, 5, respectively, were obtained. The reaction of 3, 5 and of 1,3,5-trimethylbiuret 6 with a range of P(III) chloro compounds has furnished the new 4,6-dioxo-1,3,5,2 λ3-triazaphosphinanes, 7-16. The characterization of 7-16 rests, especially, on their 1H, 13C and 31P NMR, and mass spectra.
