Abstract:


The deoxygenation of phosphine oxides was studied on two model reactions, on the reduction of 3- methyl-1-phenyl-3-phospholene 1-oxide and triphenylphosphine oxide using an aralkylsilane, arylsilanes, diarylsilanes, a disiloxane, a polysiloxane and a disilane under solvent-free, thermal or microwave-assisted conditions. The deoxygenations were optimized, and the reactivity of the silanes was evaluated. User-friendly accomplishments were elaborated.
