Synthesis and vibrational spectra of new bis(alkoxysulfane)-dichloropalladium(II) complexes and X-ray structural analysis of [PdCl2{S(OPri)2}2]

Diverse Reactivity of Platinum SF3 and SF2 Complexes towards EtOH and Me3SiOEt

“…[6] The sulfur atom exhibits an approximately tetrahedral orientation of the Pt1, O1, O2 atoms and an electron lone pair occupying (angles:O 1-S1-O2 104.28(8)8;P t1-S1-O1 105.67(5)8;P t1-S1-O2 104.16 (5)8). [13] IR measurements are in accordance with the presence of an [HF 2 ] À anion, and vibration bands at ṽ = 2743 cm À1 and 1782cm À1 were detected. [14] To the best of our knowledge the only other transition metal complexes bearing ab isalkoxysulfane ligand were described by Steudel and Wenschuh.…”

“…IR measurements are in accordance with the presence of an [HF 2 ] − anion, and vibration bands at ṽ =2743 cm −1 and 1782 cm −1 were detected . To the best of our knowledge the only other transition metal complexes bearing a bisalkoxysulfane ligand were described by Steudel and Wenschuh . The complexes [MX 2 {S(O i Pr) 2 } 2 ] (M=Pd, Pt; X=Cl, Br) were prepared by addition of S(O i Pr) 2 to MX 2 or (NH 4 ) 2 [MX 4 ].…”

“…It is also worth mentioning that complex 1 is accessible from SF 6 , of which activation reactions are of increasing interest . Note, that S(OR) X compounds are useful tools for the synthesis of organic substrates with thiosulfinate entities, which have shown considerable biological activity …”

Alkylation of a Dimolybdenum SO Bridge, Subsequent Reactions, and Characterization of the Thioperoxide Bridge

“…(Reported values for ν(SO) range from 650 to 760 cm -1 for various RSOR and related derivatives. 32,[38][39][40] The range extends to ∼800 cm -1 with strong electron withdrawal. 41,42 ) 31 P and 1 H NMR spectra gave all of the appropriate resonances.…”

“…31 Metal complexes with molecular sulfenate esters, RSOR, as ligands have also been reported. 32,33 In light of the importance and the extensive chemistry of the SO functional group in nonmetal systems, there is considerable potential for the SO group in dimetal systems. Studies of the reactivity of the SO bridge in the Mo 2 (μ-SO) complex, [Mo 2 (NTo) 2 (S 2 P(OEt) 2 ) 2 (μ-O 2 CMe)(μ-SBn)(μ-SO)], 1, have thus been undertaken.…”
