Application

Diphenylsilane serves a crucial role as a versatile reagent in various chemical transformations. It is primarily used for the deoxygenation of secondary and primary alcohols through a radical chain process, donating hydrogen atoms with the initiation of triethylborane-air. This clear, colorless liquid efficiently deaminates isonitriles and dehalogenates bromo- and iodo-compounds using radical chain chemistry. Diphenylsilane is also a key component in the preparation of fluorescent film sensors for detecting vapor-phase nitroaromatic explosives by assembling monolayers on glass surfaces. Its applications extend to the reduction of carboxylic acid derivatives, converting esters to alcohols with high yields when catalyzed by rhodium complexes. Additionally, diphenylsilane facilitates sequential C-Si bond formations, which are pivotal in developing silanediol peptide isostere precursors, and is used in various reductions, including ionic reductions of enones, reductive cyclization of unsaturated ketones, and the conversion of thio esters to ethers. It plays a role in asymmetric reductions of methyl ketones and other ketones, and aids in the reductive cleavage of allyl acetates, demonstrating its flexibility and efficacy in synthetic organic chemistry.
