Tandem-reduction of DMF with silanes via necklace-type transition over Pt(0) nanoparticles: deciphering the dual Si–H effect as an extension of steric effects

Abstract

Dimethylformamide (DMF) undergoes “double-reduction” to yield trimethylamine as a result of the concerted activation of DMF by two Si–H bonds (from different Si atoms) over Pt(0) nanoparticles as catalytic centers. Sterics on the Si atom govern the reaction and are also decisive for the structure of siloxane products due to potential limitations on the concerted activation.
