Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate, is researched, Molecular C8H12BCuF4N4, CAS is 15418-29-8, about Copper-catalyzed 1,4-alkylarylation of 1,3-enynes with masked alkyl electrophiles.Category: ruthenium-catalysts.
Classical 1,4-dicarbofunctionalization of 1,3-enynes employs organometallic reagents as nucleophiles to initiate the reaction. A copper-catalyzed 1,4-alkylarylation of 1,3-enynes with alkyl diacyl peroxides as masked alkyl electrophiles and aryl boronic acids as nucleophiles, selectively affording structurally diversified tetrasubstituted allenes under mild conditions has been reported. Mechanistic studies suggest that an allenyl radical might be involved.
As far as I know, this compound(15418-29-8)Category: ruthenium-catalysts can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
