Synthesis and structural investigation of addition reaction's yields of 1,3,2,4-dithiadiphosphetane-2,4-disulfide

In this work, some ferrocenyl dithiophosphonic acids were synthesised (Fc(RO)P(S)S-NH4+; R= -(CH2)3-C6H5), FcL1; R= -CH-(Ph)(C2H5), FcL2; R= -CH2-CH2-CH-(CH3)2, FcL3; R= -CH-(C2H5)2, FcL4) as an ammonium derivates. The new complexes of ferrocenyl dithiophosphonates were synthesised via the reaction of metal cations with ammonium dithiophosphonates ([M(Fc(RO)P(S)S)2]n, n= 1, M= Ni2+ ; n= 2, Cd2+, Hg2+ ; R= -(CH2)3-C6H5), [Ni(FcL1)2]; R= -CH-(Ph)(C2H5), [Ni(FcL2)2]; R= -CH2-CH2-CH-(CH3)2, [Ni(FcL3)2]; R= -CH-(C2H5)2, [Ni(FcL4)2]). In the first step, the ferrocenyl dithiophosphonic acids were obtained by means of reaction of between Ferrocenyl Lawesson reagent some alcohols. Then these acids were obtained their ammonium salts. Two octahedral nickel complexes were also synthesized by the reaction of some new square planar with pyridine ([Ni(Fc(RO)P(S)S)2Py2]; [Ni(FcL1)2(Py)2], [Ni(FcL22(Py)2], [Ni(FcL3)2(Py)2] ve [Ni(FcL4)2(Py)2]). The complexes ve ligands were characterized by elemental analysis, 1H-, 13C-, 31P-NMR, MS, FTIR. [Ni(FcL3)2] complex was elucidated by X-ray crystallography. Key words: Ferrocenyl dithiophosphonate, ferrocenyl dithiophosphonate complexes, heterobimetalic complex, Ferrocenyl Lawesson's Reagent.
