“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] In contrast, only a handful of examples of silver-catalyzed hydrogenation and hydrosilylation are known. [15][16][17][18][19][20] For example, AgOTf has been shown to catalyze the hydrosilylation of aryl aldehydes in the presence of Me 2 PhSiH and PEt 3 .…”

Asymmetric Hydrosilylation of Prochiral Ketones Catalyzed by Nanocrystalline Copper(II) Oxide

“…[12] The effectiveness of [CuH·PPh 3 ] 6 for the hydrosilylation of carbonyl compounds was reported by Lipshutz. [13] Subsequent studies by the same group led to the development of the highly enantioselective hydrosilylation of ketones based on CuCl/NaO-t-Bu and chiral diphosphine ligands. [14] Besides Strykers reagent and copper alkoxides, copper fluoride [15] and copper(II) acetate [16] also catalyze the AHS reaction of prochiral ketones in the presence of BINAP ligand.…”

Synthetic Applications of Stryker’s Reagent

“…10 (B) With Stryker's reagent, the conjugate reduction of nitroalkenes is followed by intramolecular aldol reaction (Henry reaction) to produce b-nitroalcohols in modest to good yield. …”
