Tri(cyclohexa-2,5-dien-1-yl)silane: A Stable and Easy-to-handle Surrogate of Monosilane (SiH4)
Synthesis of multisubstituted silanes:
In a glove box, a Schlenk tube is charged with an alkene (0.300 mmol). In two vials are weighed B(C6F5)3 (7.7 mg, 15 µmol) and tri(cyclohexa-2,5-dien-1-yl)silane (1, 28.0 mg, 0.105 mmol). All the sealed containers are taken out of the glove box, and the Schlenk tube is connected to a N2 line. Under a N2 counterflow are subsequently added 0.3 mL of CH2Cl2, 1 then B(C6F5)3. The tube is completely sealed and stirred at room temperature for 24 h. After this time, two drops of triethylamine are added to the solution under an N2 counterflow, and the resulting mixture is stirred for 5 min before being filtered over a short alumina column (elution with CH2Cl2). After evaporation of all volatiles, the crude product is purified by flash column chromatography to give the multisubstituted silane 3.
