CO Reduction to CH3OSiMe3: Electrophile-Promoted Hydride Migration at a Single Fe Site
Deegan, Meaghan M.,Peters, Jonas C.
, p. 2561 - 2564 (2017)
One of the major challenges associated with developing molecular Fischer-Tropsch catalysts is the design of systems that promote the formation of C-H bonds from H2 and CO while also facilitating the release of the resulting CO-derived organic products. To this end, we describe the synthesis of reduced iron-hydride/carbonyl complexes that enable an electrophile-promoted hydride migration process, resulting in the reduction of coordinated CO to a siloxymethyl (LnFe-CH2OSiMe3) group. Intramolecular hydride-to-CO migrations are extremely rare, and to our knowledge the system described herein is the first example where such a process can be accessed from a thermally stable M(CO)(H) complex. Further addition of H2 to LnFe-CH2OSiMe3 releases CH3OSiMe3, demonstrating net four-electron reduction of CO to CH3OSiMe3 at a single Fe site.

1,1,3,3-Tetramethylguanidine (TMG) and 2-(trimethylsilyl)-1,1,3,3-tetramethyl-guanidine (TMSTMG) react with trimethylhalosilanes Me3SiHal in equimolar ratio with ionization of the Si-halogen bond to give the stable guanidinium salts Hal (
Novel 10-I-3 hypervalent iodine-based compounds for electrophilic trifluoromethylation
Eisenberger, Patrick,Gischig, Sebastian,Togni, Antonio
, p. 2579 - 2586 (2006)
The synthesis of a new family of 10-I-3 hypervalent iodine compounds is described in which the CF3 functionality participates directly in the hypervalent bond. These materials are accessible by nucleophilic ligand substitution at iodine using Me3SiCF3 in the presence of a substoichiometric amount of fluoride. The expected T-shaped geometry at iodine was verified by X-ray crystallographic analyses of three of the products (1-trifluoromethyl-1,2-benziodoxol-3-(1 H)-one and two substituted 1-trifluoromethyl-1,3-dihydro-1,2-benziodoxoles). Preliminary results for the direct electrophilic transfer of the trifluoromethyl moiety onto organic nucleophiles show modest reactivity in polar aprotic solvents under relatively mild conditions. The overall process can be understood as a formal umpolung of the CF3 group.
Catalytic Disproportionation of Formic Acid to Methanol by using Recyclable Silylformates

supporting information, p. 14019 - 14023 (2020/06/09)
A novel strategy to prepare methanol from formic acid without an external reductant is presented. The overall process described herein consists of the disproportionation of silyl formates to methoxysilanes, catalyzed by ruthenium complexes, and the production of methanol by simple hydrolysis. Aqueous solutions of MeOH (>1 mL, >70 percent yield) were prepared in this manner. The sustainability of the reaction has been established by recycling of the silicon-containing by-products with inexpensive, readily available, and environmentally benign reagents.
