 Title    Organophosphorus Compounds of Expected Biological Activity, Part II* Preparation of Thiourea Derivatives and N-Aryl-phosphorothiomonoamidates  
 Abstract    The examples of cyclodiphosphazanes so far studied do not contain any nuclei of biological interest [1]. In the present investigation we aimed to introduce ethyl p-amino-benzoate, 2-aminopyridine residues in the phosphazane molecule. For this purpose phos-phorus pentachloride was treated with ethyl p-aminobenzoate, p-anisidine, 2-amino-pyridine and 5-aminoquinoline to give l,3-di-j9-ethoxycarbonylphenyl-, l,3-di-j9-methoxy-phenyl-, l,3-di-2-pyridyl-and l,3-di-5-quinolinyl-2,2,2,4,4,4-hexachlorocyclo-diphos-phazane (la-d), respectively. The compounds la-d were treated with potassium thio-cyanate in acetone. The oily products formed were then treated with p-anisidine, ethyl-p-aminobenzoate and 2-aminopyridine whereupon solid products (2a-h) were obtained. The reaction probably takes place according to the following mechanism [2]. la: b: c: d: Ar 1 Ar C2H5OOCC6H4-(p) CH3OC6H4-(p) C5H4N-(2) C9H6N-(5) Ar Cl /N Cl ci >0< ci SCN NCS 2a: b: c:
