Heterocyclization and solvent interception upon oxidative triflamidation of allyl ethers, amines and silanes
Ganin, Anton S.,Moskalik, Mikhail Yu.,Astakhova, Vera V.,Sterkhova, Irina V.,Shainyan, Bagrat A.
, (2020)
The reactions of triflamide with a series of mono- and diallyl heteroatomic compounds have been studied in the presence of various oxidants (t-BuOI, NBS, NIS). The reaction course was found to be strongly dependent on the oxidant leading to the products of bis(triflamidation) or heterocyclization in the system (t-BuOCl + NaI), or amidines – the Ritter-type solvent interception halosulfamidation products – with N-bromo- or N-iodosuccinimide. The amidines were converted to imidazolines in high yield via the base-induced heterocyclization.
An Efficient Catalyst for the Conversion of Hydrosilanes to Alkoxysilanes

The copper(I) hydride 6 is an efficient catalyst for the alcoholysis of primary and secondary silanes.The reactions proceed at room temperature within a few hours and give the alkoxysilanes in high yields.Only with bulky alcohols or silanes are longer reaction times and/or increased temperatures required.The presence of air accelarates the reactions and gives rise to higher yields of alkoxysilanes, particularly with bulky alcohols.Diols react with PhRSiH2 (R = Me, Ph) to afford 1,3-dioxo-2-silacycloalkanes and with tertiary silanes to furnish the bissilylated diols.When unsaturated alcohols (2-propen-1-ol or 2-propyn-1-ol) are employed, the double or triple bond is retained. - Keywords: Catalytic silane alcoholysis; Alkoxysilanes
Carbanion mechanisms XVIII. Generation of silyl anions by nucleophilic cleavage of disilanes
Buncel, Erwin,Venkatachalam, T. Krishnan,Edlund, U.
, p. 85 - 89 (2007/10/02)
Organosilyl potassium compounds are conveniently generated by cleavage of hexaorganodisilanes with potassium t-butoxide in common solvents other than HMPA (i.e. in THF or DME).Nucleophilic attack on unsymmetrical disilanes results in formation of the more
