Investigation on the reactivity of dithiophosphonato/dithiophosphato NiII complexes towards 2,4,6-tris-2-pyridyl-1,3,5-triazine: Developments and new perspectives

The reactions between tptz and differently substituted dithiophosphonato [Ni(ROpdt)2] [ROpdt = (RO)(4-MeOC6H4)PS 2-; R = Et (2); Pr (3); i-Pr (4); Bu (5)] and dithiophosphato [Ni((EtO)2PS2)2] (6) Ni II complexes have been investigated, and the characterisation of the resulting neutral mixed complexes (2·tptz)-(6·tptz) is reported. In all these complexes, tptz forces one of the two dithiophosphonato/ dithiophosphato ligands to behave as a monodentate ligand, a coordination mode rarely found in analogous NiII phosphorodithioato complexes. A comparison has been performed between the Ni-S bond distances of the new complexes and those of isologous dithiophosphonato, dithiophosphato and dithiophosphito NiII square-planar complexes, and of their penta- and hexa-coordinated adducts. The results, also supported by DFT calculations, are discussed and explained in terms of the structural trans-effect (STE). The reactivity of 2·tptz towards AgNO3 and CuSO4 to yield the complex [Ni(EtOpdt)(tptz)(H2O)]NO3 (7), and the dimer [(Ni(tptz)(μ-SO4)(H2O)]2· 6H2O (8), respectively, is consistent with the proposed bonding models.

Alkyl transfer reactivity in the first octahedral isocyanide complex of nickel(II)

[Ni{S2P(OEt)2}2] (1) reacts with 2 equiv of CNXyl (Xyl = 2,6-dimethylphenyl) to afford [Ni{S2P(OEt) 2}2(CNXyl)2] (2), which, as confirmed by X-ray crystallography, is the first octahedral isocyanide complex of Ni(II). Reaction of 2 with PCy3 (2 equiv) produces square-planar [Ni{S 2P(O)(OEt)}(PCy3)(CNXyl)] (3). When 2 is reacted with only 1 equiv of PCy3, the final product is the square-planar complex [Ni{S2P(O)(OEt)}(CNXyl)2] (4), containing two isocyanide ligands. Compound 4 reacts with 2-fold excess PCy3 to give 3 via isocyanide displacement. Both 3 and 4 contain one ethyldithiophosphate ligand, which is produced by the transfer of one ethyl group from a coordinated diethyl dithiophosphate of complex 2 to the leaving diethyl dithiophosphate ligand. Experimental evidence indicates that the phosphine plays a significant role in the alkyl transfer. Moreover, reaction of 1 with 2 equiv of N-p-tolyl-2- iminopyridine affords octahedral [Ni{S2P(OEt)2}{2-pyCH= NC6H4-Me-4}2][S2P-(OEt) 2] (5), in which both free and coordinated diethyl dithiophosphate coexist without any transfer of alkyl.

LIGAND EXCHANGE REACTIONS OF ANTIMONY(III) O,O-DISUBSTITUTED PHOSPHORODITHIOATES WITH NICKEL SALTS

Antimony(III) tris-(O,O-dialkyl phosphorodithioates) undergo ligand exchange reactions with nickel(II) chloride or nickel(II) octanoate in tetrahydrofuran solution to give nickel(II) bis-(O,O-dialkyl phosphorodithioates).The rates of the exchange reactions with nickel(II) chloride have been measured, and the rate constants can be correlated with polar substituent constants by use of the Taft-Hammett equation.The results suggest that the ligand exchange reactions occur by an initial SN2 type of attack of chloride ion on the antimony atom of the antimony(III) tris-(O,O-dialkyl phosphorodithioates).
