Notes:
Room temperature reactions of S4N4 with (amino) diphenylphosphines, (R)Ph2P, have basically yielded two different types of S—N heterocycles under two different stoichiometric conditions. Phosphiniminocyclotrithiatriazenes, (R)Ph2PN—S3N3 (R = C4H8N—, C5H10N—, C6H12N—, CH3NC4H8N—, (C6H11)2 N—, and (C6H5CH2)2N—) have been obtained (yield 45-76%) from a 1:2 mole ratio (S4N4:(R)Ph2P) reaction, while the disubstituted S4N4 derivatives, 1,5-[Ph2(R)PN]2S4N4 (R = C4N8N—, C5H10N—, and C6H12N—) have been obtained (yield 30-45%) only from a 1:3.5-4 mole ratio reaction. All the 1,5-[Ph2(R)PN]2S4N4 derivatives prepared in this study undergo a room temperature solution phase transformation to the corresponding (R)Ph2PN—S3N3 heterocycles.
