Studies on Heterocyclic Primary Amines, P3rt n Synthesis of 5-AryI-2-(diarylph08phoramido) and (p-tolyl Sulfanilamido )-1 ,3,4-Oxadiazoles

2-Amino-S-Aryl-l,s,3.~actiazo1es have been condensed with diphenylphosporyl chloride and p-toluenesulfonyl chloride to give the corresponding phosphol8l11ido and sulfanilamido derivativeL The di-p-nitrophosphol8l11ido derivatives were prepared from phosphol8l11idic dichlorides and sodiuni p-nitrophenatc, The structures have been confinned by correct analytical data and IR spectral studies.
