Sodium 1,1,1-Trifluoromethanesulfonate

Comprehensive Experimental and Computational Study of η6-Arene Ruthenium(II) and Osmium(II) Complexes Supported by Sulfur Analogues of the β-Diketiminate Ligand

“…Following the methodology developed for cationic η 6 -arene Ru­(II)- and Os­(II)-β-diketiminate complexes 2a – d , chlorido substituents 5a – c and 6 are readily abstracted using sodium or sliver salts featuring weakly coordinating anions, i.e., tetrakis -3,5-bis­(trifluoromethyl)­phenyl borate (herein abbreviated as BArF) or PF 6 (Method A, Scheme ). Moreover, formation of the triflate salts is a convenient one-pot procedure using a slight excess of [Na]­OTf with lithiated 3b or 3c in the presence of the η 6 -arene Ru chloride dimer (Scheme , Method B) …”

“…Moreover, formation of the triflate salts is a convenient one-pot procedure using a slight excess of [Na]OTf with lithiated 3b or 3c in the presence of the η 6 -arene Ru chloride dimer (Scheme 7, Method B). 53 The resulting brown or dark green colored complexes are isolated in yields of 33−68%. Sensitivity of the cationic complexes to air and moisture was significantly more extreme than that of the chloride-substituted analogues, with exposure in the solid state or solution causing visible decomposition within minutes.…”

Pd-Catalyzed Conjunctive Cross-Coupling between Grignard-Derived Boron “Ate” Complexes and C(sp2) Halides or Triflates: NaOTf as a Grignard Activator and Halide Scavenger

“…Of note, NaOTf 31 is a commercially available and inexpensive salt. After optimization of sol-vent ( vide infra for discussion of solvent effects), catalyst loading, stoichiometry, reaction time and temperature (see SI, Table S2), the optimal set of conditions were found to be as depicted in equation 4.…”

“…Considering the remarkable difference in solubility between NaOTf and NaCl, as well as the ability of NaOTf to promote “ate” complex formation from Grignard reagents, this additive was examined in conjunctive coupling reactions that employ vinylmagnesium chloride. Of note, NaOTf is a commercially available and inexpensive salt. After optimization of solvent (vide infra for discussion of solvent effects), catalyst loading, stoichiometry, reaction time and temperature (see SI, Table S2), the optimal set of conditions were found to be as depicted in eq .…”
