Abstract
Cyclic phosphorus-nitrogen compounds were used as stabilizing substituents for the preparation of compounds with elements of different formal oxidation states. The starting materials were P3N3F6, N[Sn(CH3)3]3 and ClSO2-CH2SO2C1 which yield the methane substitued derivative P3N3F5N-SO2-CH2-SO2-N[sbnd]P3-N3F5 3. SCl2 and CH3 PCl2 react Sn(CH3)3 (CH3)3Sn with 2 to form the cyclic compounds
