Some highly sterically hindered organosilicon compounds
The chemistry of organometallic compounds with bulky ligands such as (Me3Si)3C(Tsi) or (Me2PhSI)3C(Tpsi) attached to a variety of metal centres is reviewed. The compounds Tsi2M (M = Zn, Cd, Hg) and the rare two co-ordinate TsiMn show exceptional thermal and hydrolytic stability. The corresponding alkylmetal halides form ring or cage structures. In a range of new boron compounds the structures o...

متن کاملPractical catalytic method for synthesis of sterically hindered anilines.
A practical catalytic method for the synthesis of sterically hindered anilines is described. The amination of aryl and heteroaryl boronic esters is accomplished using a catalyst prepared in situ from commercially available and air-stable copper(i) triflate and diphosphine ligand. For the first time, the method can be applied to the synthesis of both secondary and tertiary anilines in the presen...
متن کاملIncreased efficiency in cross-metathesis reactions of sterically hindered olefins.
Efficiency in olefin cross-metathesis reactions is affected upon reducing the steric bulk of N-heterocyclic carbene ligands of ruthenium-based catalysts. For the formation of disubstituted olefins containing one or more allylic substituents, the catalyst bearing N-tolyl groups is more efficient than the corresponding N-mesityl catalyst. In contrast, the formation of trisubstituted olefins is mo...
متن کاملFlow carbonylation of sterically hindered ortho-substituted iodoarenes
The flow synthesis of ortho-substituted carboxylic acids, using carbon monoxide gas, has been studied for a number of substrates. The optimised conditions make use of a simple catalyst system compromising of triphenylphosphine as the ligand and palladium acetate as the pre-catalyst. Carbon monoxide was introduced via a reverse "tube-in-tube" flow reactor at elevated pressures to give yields of ...
