Cobalt-Catalyzed Intramolecular Silylperoxidation of Unsaturated Diisopropylsilyl Ethers
Oswald, Jonathan P.,Woerpel
, p. 7564 - 7574 (2019/06/17)
A cobalt-catalyzed intramolecular silylperoxidation reaction was developed that allows for the conversion of unsaturated diisopropylsilyl ethers to 3-sila-1,2,4-trioxepanes. Reduction of the peroxide unit of the 3-sila-1,2,4-trioxepane yields six-membered

experimental part, p. 5793 - 5802 (2012/01/14)
Pentamethylcyclopentadienyl ruthenium(II) complexes with picolyl-functionalized N-heterocyclic carbenes [(η5-C 5Me5)-Ru(L)(CH3CN)][PF6] (L = 3-methyl-1-(2-picolyl)imidazol-2-ylidene (1a), 3-isopropyl-1-(2-picolyl) imidazol-2-ylidene (1b), 3-phenyl-1-(2-picolyl)imidazol-2-ylidene (1c), 3-mesityl-1-(2-picolyl)imidazol-2-ylidene (1d), 3-methyl-1-(2-picolyl) benzoimidazol-2-ylidene (1e), 3-methyl-1-(2-picolyl)-4,5-dichloroimidazol-2- ylidene (1f)) have been synthesized and characterized. Compounds 1a,b were recrystallized as BAr4 F salts (anion BAr4 F- = tetrakis(3,5-bis(trifluoromethyl)phenyl)borate), giving 2a,b. X-ray crystal structures of the acetonitrile adduct 2a and the dioxygen compound 2b are also reported. Furthermore, carbonyl derivatives 3a-f have been prepared, characterized, and used to study the donor properties of the picolylcarbene ligands(l) via infrared spectroscopy. Compounds 1a-f show catalytic activity in transfer hydrogenation of ketones. Notably, complex 1a was found to be a very efficient and versatile catalyst toward transfer hydrogenation of a wide range of ketones and imines.
Hindered organoboron groups in organic chemistry. 21. The reactions of dimesitylboron stabilised carbanions with oxiranes
Peter, Andrew,Vaughan-Williams, Gina F.,Rosser, Richard M.
, p. 3007 - 3034 (2007/10/02)
Dimesitylboron stabilised carbanions react with oxiranes to give products that can be oxidised to 1,3-diols. The reactions are, in general, under steric rather than electronic control, and proceed smoothly for all but tetrasubstituted oxiranes. Some unusual stereoselective effects have been observed.
The Regiochemistry and Stereochemistry of the Hydroboration of Allylsilanes
Fleming, Ian,Lawrence, Nicholas J.
, p. 3309 - 3326 (2007/10/02)
The hydroboration of a wide range of allylsilanes 3 and 5-21 is found to be generally regioselective for attachment of the boron to C-3 and hydrogen to C-2 of the allyl unit, and to be generally stereoselective in the sense 1, with attachment of the boron
STEREOSELECTIVITY IN THE HYDROBORATION OF CHIRAL CYCLOHEXANE-DERIVED ALLYLIC ALCOHOLS
Birtwistle, David H.,Brown, John M.,Foxton, Michael W.
