[dimethyl(phenyl)silyl]oxy-dimethyl-phenylsilane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: An acetonitrile solution of [Re(O)(hoz)2][B(C6F5)] (0.050 g, 0.040 mmol) was treated with water (3 mL, 166 mmol) in a Schlenk tube. Phenyldimethyl silane (1 mL, 6.53 mmol) was then added and the evolution of hydrogen was monitored using a glass evolution apparatus. Upon cessation of hydrogen evolution the reaction mixture was poured onto ice and treated with pentane to precipitate the catalyst. The mixture was filtered and the organic layer was extracted with diethyl ether and pentane. The solution was dried with anhydrous MgSO4 and filtered. Pentane and ether were removed in vacuo to afford 88% isolated yield of PhMe2Si(OH) (95%) and (PhMe2Si)2O (5%). to precipitate the catalyst The mixture was filtered the organic layer was extracted with diethyl ether and pentane The solution was dried with anhydrous MgSO4 filtered Pentane and ether were removed in vacuo to afford 88%

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Five millimoles of 1,1,1,3,5,5,5-heptamethyltrisiloxane, 5 mmol of dimethylphenylvinylsilane, and 5 mmol of dimethylethoxyphenylsilane were mixed. To the mixture were added 5 mmol of water, 5×10-4 mmol of a platinum-vinylsiloxane complex, and 0.1 mmol of hydrochloric acid, followed by stirring at room temperature for 3 hours. Quantitative determination of the reaction product by gas chromatography revealed that 2,2-di-trimethylsiloxy-5-phenyl-5-methyl-2,5-disilahexane was obtained in a yield of 99% as a hydrosilylation addition product and 1,3-diphenyl-1,1,3,3-tetramethyldisiloxane was obtained in a yield of 99% as an alkoxysilane condensation product. was obtained in a yield of 99% as a hydrosilylation addition product
