Cyclic sulphur–nitrogen compounds and phosphorus reagents. Part 2. Reactions of tetrasulphur tetranitride with (morpholino)diphenylphosphine. First observation of the ring contraction of 1,5-[(OC4H8N)Ph2PN]2S4N4 to (OC4H8N)Ph2PNS3N3 in solution
TLDR
In this paper, a ring contraction of compound (2) to compound (1) in solution at room temperature has been observed and evidence for the elimination of the NSR group (R = phosphinimino group) obtained.Abstract:
(Morpholino)diphenylphosphine, unlike PPh3, gives only two new compounds, (OC4H8N)Ph2PNS3N3, (1), and 1,5-[(OC4H8N)Ph2PN]2S4N4, (2), on reacting with S4N4. The reaction temperature, solvent, and mole ratio of the reactants are critically important in their synthesis. For the first a ring contraction of compound (2) to compound (1) in solution at room temperature has been observed and evidence for the elimination of the ‘NSR’ group (R = phosphinimino group) obtained.read more

Aminophosphines: their chemistry and role as ligands and synthons
TL;DR: The chemistry of simple acyclic aminophosphines (synthesis, characterization, reactivity and applications) is covered and particular focus is given to their ability to form chalcogenides along with their role played as ligands in coordination chemistry and as synthons in inorganic heterocyclic chemistry as mentioned in this paper.

A new synthetic route to cyclophosphadithiatriazenes: synthesis and X-ray structural characterization of the first spirocycle containing thiadiazaphosphetidine and phosphadithiatriazene heterocycles
TL;DR: The spiro phosphorus atom subtends a four-membered PVSVIN2 ring which is saturated, and a sixmembered PVSN3 ring which are unsaturated as mentioned in this paper, which reveals a planar PSN2 ring and a puckered PS2N3 ring and the molecule is symmetric in nature.
