Two novel perthiophosphonic acid anhydrides, 2,4-bis(R x,y)-1,3-dithia-2,4-diphosphetane 2,4disulfide [(R x,y-P(S)S)2; R x =3-methoxytolyl (SAV-B1) and R y =2-methoxytolyl (SAV-B2)] were synthesized. From the reaction of SAV-B1 and SAV-B2 with alcohols, four new dithiophosphonic acids [HS2P(R x,y)(ORn)] (Rn; R1=ethyl R2=2-propyl) were prepared. These acids were converted to corresponding ammonium salts, [NH4][S2P(R x,y)(ORn)]. The ammonium salts were further reacted with NiCl2.6H2O to prepare four new dithiophosphonato nickel(II) complexes, [Ni(S2P(R x,y)(ORn))2]. The ligands and complexes were characterized by elemental analyses, IR, ESI-MS, 1D 1 H, 13 C, 31 P NMR and 2D HSQC techniques. Complementary structural information was provided by the HSQC spectrum of the [NH4][S2P(R x,y)(OR2)]. The structure of the perthiophosphonic acid anhydrides was deduced from the structures of dithiophosphonates thereof.

“…Moreover, small phosphorus‐chalcogen heterocycles that display asymmetry with respect to the 4‐membered core are even rarer. These include P‐S‐P‐E (Figure , G ), P‐Ch‐P‐C (Ch=S, Se, H ), P‐S‐C‐S ( I ), and P‐S‐C‐C structures ( J ), amongst others . Small ring cores that contain asymmetry in the presence of a P−P bond are by far the rarest, with published examples limited to only three species: P‐P‐C‐N ( K ), P‐P‐C‐O ( L ), and P‐P‐Si‐N ( M ) .…”

Four-membered rings with a P BCh core (Ch=S, Se) have been synthesized by the reaction of phosphinidene chalcogenide (Ar*P=Ch) and phosphaborene (Mes*P=BNR ). The mechanistic pathways towards these rings are explained by detailed computational work that confirmed the preference for the formation of P-P, not P-B, bonded systems, which seems counterintuitive given that both phosphorus atoms contain bulky ligands. The reactivity of the newly synthesized heterocycles, as well as that of the known (RPCh) rings (n=2, 3), was probed by the addition of N-heterocyclic carbenes, which revealed that all investigated compounds can act as sources of low-coordinate phosphorus species.
