“…Phosphinocarbodithioates (Figure a) have been widely used as ambidentate ligands in coordination chemistry to bind lead(IV), , mercury(II), tin(IV), and iron(II) via the S atom or to niobium(II) and tungsten(II) via the P atom. The phosphacarbodithioate structural motif often acts as a bidentate ligand in complexes with ruthenium and iron that mimic certain biological systems.…”

Synthesis of S-Alkyl Phosphinocarbodithioates with Switch between P(III) and P(V) Derivatives

Compound 9 is the first example of carbodithioate ester with a P=Se group and for the first time a phosphinocarboditioate with a free phosphine function (compound 10) is described. Stabilization of the latter crucially depends on the steric protection by the t-Bu groups, since an analogous derivative with R = Ph is observable but too unstable for isolation. Compound 10 can be reversibly protonated to yield the [t-Bu2PHC(S)SCH(Me)Ph] + cation (10-H +), which was isolated as a BF4salt. A few interconversion processes resulting in the facile addition/removal or exchange of the X group in this family of compounds are also described. The phosphorus atom oxidation state and the nature of electron-withdrawing group have a significant impact on the spectral properties.

Coordination Properties of Non-Rigid Phosphinoyldithioformate Complexes of the [Mo2O2(µ-S)2]2+ Cation in Catalytic Sulfur Transfer Reactions with Thiiranes

Two “Mo2O2S2”-based complexes with phosphinoyldithioformate ligands were synthesized from the metathesis reaction of [R2P(O)CS2]− with (Me4N)2[Mo2O2(µ-S)2(Cl)4] to give [Mo2O2(µ-S)2{R2P(O)CS2}2] (1; R = Ph, 2; R = Bn). The complexes were fully characterized, including the X-ray crystal structure for 1. Variable temperatures 31P NMR of 1 and 2 exhibit non-rigid behavior in solution where three and two coordination isomers were present, respectively. The organic substituent on the P atom greatly impacts the complex non-rigid properties and behavior. The catalytic activity of 1 and 2 towards sulfur atom transfer (SAT) using propylene sulfide and cyclohexene sulfide was explored, employing homogeneous reaction conditions at an ambient temperature on the NMR scale. The complexes showed distinctly different properties along with high conversions in short reaction times. A catalytic cycle consistent with the results is proposed.
