Direct Synthesis β-Acyloxy Aldehydes from Linear Allylic Esters Using O2 as Sole Oxidant

A simple and practical preparation of β-O substituted aldehydes directly from linear allylic esters is developed. Using bis(benzonitrile)palladium chloride as the catalyst and O2 as sole oxidant, the tandem isomerization-...

Direct synthesis of tetraalkoxysilanes in a high-pressure mechanochemical reactor.

We report the results of studies on the direct synthesis of tetraalkoxysilanes from alcohols and metallic silicon in a high-pressure mechanochemical reactor. The effect of the following factors on the...

Rh(III)-catalyzed annulated coupling of sulfoxonium ylides and iodonium ylides: a rapid access to isocoumarins

Direct synthesis of isocoumarin skeletons has been realized through Rh(III)-Catalyzed [3 + 3] annulation of sulfoxonium ylides and iodonium carbenes. The synthetic protocol constructed efficiently with the broad functional group...

Cu(i) catalysis for selective condensation/bicycloaromatization of two different arylalkynes: direct and general construction of functionalized C–N axial biaryl compounds

Selective condensation/bicycloaromatization of two different arylalkynes is firstly developed under ligand-free copper(i)-catalysis, which allows the direct synthesis of C–N axial biaryl compounds in high yields with excellent selectivity and functional group tolerance.
