Abstract :Two new perthiophosphonic acid anhydrides, 2,4-bisinsert ignore into journalissuearticles values(Rx,y);-1,3-dithia-2,4-diphosphetane 2,4-disulfide insert ignore into journalissuearticles values(Rx=3-methoxytolyle, SAV-B1 and Ry=2-methoxytolyle, SAV-B2); were synthesized. From the reaction of these dimers, insert ignore into journalissuearticles values(Rx,y‐Pinsert ignore into journalissuearticles values(S);S);2, with alcohols and then dry ammonia gas, ammonium salts of the dithiophosphonic acids insert ignore into journalissuearticles values(insert ignore into journalissuearticles values(Rx,y);insert ignore into journalissuearticles values(RnO);PS2H);, Rn, R1= ethyl-, R2= 2-propyl-);, namely, four new compounds of the type [NH4][S2Pinsert ignore into journalissuearticles values(Rx,y);insert ignore into journalissuearticles values(ORn);] were obtained. The ammonium salts were further reacted with NiCl2.6H2O to prepare four new dithiophosphonato nickelinsert ignore into journalissuearticles values(II); complexes, [Niinsert ignore into journalissuearticles values(S2Pinsert ignore into journalissuearticles values(Rx,y);insert ignore into journalissuearticles values(ORn););]. The ligands and the complexes were characterized by mass-insert ignore into journalissuearticles values(ESI);, 1H-, 13C-, 31P-NMR, IR-spectroscopy, HSQC techniques and elemental analyses. Complementary structural information was provided by the HSQC spectra of the [NH4][S2Pinsert ignore into journalissuearticles values(Rx,y);insert ignore into journalissuearticles values(OR2);]. The structure of the perthiophosphonic acid anhydrides were deduced from the structures of dithiophosphonates thereof.
