Synthesis and characterization of cyclopalladated and non-cyclopalladated complexes of ligands containing the 1,3-bis(thiomethyl)benzene unit

Palladium(II) Compounds with Fluorinated Pincer‐Type (SCS) Ligands: X‐ray Structures of C6H4‐1,3‐(CH2SC6H4F‐4)2 and [PdCl(SCS–Rf)] [Rf = C6H4F‐2, C6H4F‐3, C6H4F‐4, C6H4(CF3)‐2, and C6H4(CF3)‐4]

“…In compounds 4 and 6 , the Pd atoms are also in a slightly distorted square‐planar environment: S(1)–Pd(1)–S(2), 4 171.54(2); 6 165.99(4)° and Cl(1)–Pd(1)–C(1), 4 178.46(7); 6 176.82(13)°. The bonding parameters for Pd are comparable with those observed for complexes 1 – 3 and analogous compounds 19f,29–31. The C 6 H 4 (CF 3 )‐ n ( n = 2 or 4) groups attached to the metal‐bound sulfur atoms are oriented in an anti fashion with respect to the square plane, as is the case for 1 and 2 .…”

“…The C 6 H 4 F‐2 and C 6 H 4 F‐3 groups attached to the metal‐bound sulfur atoms in 1 and 2 are oriented in an anti fashion with respect to the square plane; a common conformation observed in these type of compounds,19f,29–31 which allows for minimization of any steric repulsions between the aromatic rings. In contrast, the C 6 H 4 F‐4 groups attached to the metal‐bound sulfur atoms in 3 are oriented in a syn fashion with respect to the square plane; this allows for maximization of intermolecular aromatic π‐stacking interactions between the metalated rings in adjacent molecules at ca.…”

Tiara-like Octanuclear Palladium(II) and Platinum(II) Thiolates and Their Inclusion Complexes with Dihalo- or Iodoalkanes

“…[44][45] When the same reaction was performed at room temperature, it produced an insoluble solid in nearly quantitative yield; the product appeared to be a monomer and/or oligomers of Pd1-C1 = 1.980(2), Pd1-S1 = 2.2967 (7), Pd1-S2 = 2.3151 (7), Pd1-Cl1 = 2.3961 (7), C1-Pd1-S1 = 83.11(6), C1-Pd1-S2 = 84.46(6), S1-Pd1-Cl1 = 96.27(3), S2-Pd1-Cl1 = 96.12(2), Pd1-S1-C2 = 99.24 (7), Pd1-S1-C4 = 105.61 (7), C2-S1-C4 = 104.64(10), Pd1-S2-C3 = 97.67 (7), Pd1-S2-C5 = 102.18 (7), C3-S2-C5 = 100.81(11), C1-Pd1-S1-C2 = 25.12 (10) by HCl followed by E1 elimination similar to that described above occurs again to give 4 and a mononuclear palladium thiolate, [Pd(SCH 2 CO 2 Me) 2 ], which then aggregates to construct a stable tiara-like octanuclear architecture. Although the above mechanism explains the formation of 1, the bidentate coordination of 2 to PdCl 2 without aromatic C(sp 2 )-H bond activation 45 and the subsequent stepwise elimination of the thiolate groups, similar to the above mechanism, can proceed concurrently to form 1.…”

Benzyl 2-(benzylsulfanyl)benzoate

“…The specific property of the present compound is that the atoms S1, C15 are C16 all lie in the plane of the central ring within 0.03 Å. In the cases of similar uncoordinated (Sillanpää et al, 1994;Alhadi et al, 2010] as well as coordinated ligands (Radić et al, 2012;Lucena et al, 1996)…”
