✦ Synopsis

PzNOC15 ( I ) , P P N C I ~ (21, and P4N30C19 (3) were clarified by measuring the nuclear magnetic resonance of the 31P atom. N. M. R. spectra of 3iP were also used to determine the qualitative and quantitative compositions of the complex reaction mixture which is obtained when S4N4 reacts with CsHsPC12. This mixture contains the compounds (4)-( 7), so far unknown, in addition to phenyldichloro-phosphine sulfide (8), the main products being compounds ( 4 ) , (7), and (8). Compound ( 4 ) can also be obtained either by treating CsHsPClz with NC13 (in the presence of PCl3, the corresponding hexachlorophosphate is obtained), or by treating phenylphosphorus tetrachloride with ammonium chloride. Starting from (41, the hitherto unknown free acid ( 9 ) is obtained by hydrolysis, its trichloride (10) by reaction of ( 4 ) with SO2,
