Significance
This paper describes two novel interesting reactions of aryltrialkoxysilanes: nucleophilic 1,2-addition of the aryl moiety to aldehydes and the oxidation of aldehydes by alkoxysilanes to the corresponding esters, promoted by palladium-phosphinous acid catalytic species. Since aryltrimethoxysilanes are stable, easy-to-handle compounds, the first reaction can serve as a convenient synthetic way to diarylcarbinols. In the second process, cheap Si(OMe)4 can be used as the oxidant, which makes this method very attractive for the direct transformation of aldehydes into the corresponding methyl esters.
