Synthesis of Arylsilanes via Palladium(0)-Catalyzed Silylation of Aryl Halides with Hydrosilane

Diphenylphosphinite ionic liquid (IL-OPPh2): A solvent and ligand for palladium-catalyzed silylation and dehalogenation reaction of aryl halides with triethylsilane

“…Another method is the catalytic conversion of C-H bonds to C-Si bonds in the presence of transition-metal complexes [5,6]. Different research groups separately reported on the transition-metal-catalyzed coupling reaction of aryl halides with trialkoxysilanes [7][8][9][10][11]. Although, trialkylsilanes (e.g., Et 3 SiH) have not been found suitable silylating agent in some catalytic systems [12], recently, their use to attain the silylation of aryl halides under Pd and Pt catalysis have been reported [13,14].…”

Silicone as an organosilicon reagent for the palladium-catalyzed cross-coupling reaction

“…Although polysiloxanes bearing a substituted aryl group are not available commercially, such compounds can be synthesized using a commercially available polysiloxane bearing a silicon-hydrogen bond, PMHS [30][31][32][33] by employing the palladium-catalyzed arylation of triethoxysilane with aryl iodides developed by Masuda [34,35]. The method was applied for the arylation of PMHS as a silane species.…”

Hypervalent siloxane derivatives. An alternative to Stille and Suzuki couplings

“…Consequently, several substituted siloxanes were synthesized using a modified procedure of Masuda [20]. These siloxanes were subjected to cross coupling conditions identical to that described in Table 1.…”
