Reaction of cis-NPCl2(NSOCl)2 with n-butylamine (molar ratio 1:2) in acetonitrile leads to a mono(amino) derivative, NPCl(NHBu) (NSOCl)2. Under the same experimental conditions sec-butylamine gives a mixture of about equal amounts of NPCl(NH-s-Bu) (N

The reaction mechanism of controlled hydrolysis of the inorganic ring system (NPCl2)(2)NSOCl in the presence of KCl and 18-crown-6 has been revised and is explained from steric constraints rather than from electronic considerations. The X-ray structu

Two classes of silicon-containing polymers are described, one in which phosphazene rings are part of the polymer backbone, the other where phosphazene rings are present as pendant groups. X-ray structures of some monomeric precursors and reaction pro

The reaction of Pt(PPh3)2(C2H4) with 1,5-R4P2N4S2 (R = Ph, Et, Me) in toluene at 23-degrees-C produces the monomeric complexes Pt(PPh3)2(1,5-R4P2N4S2) (2a, R = Ph; 2b, R = Et; 2c, R = Me) as air-stable yellow solids, which were characterized by P-31
