Reaction Steps

A 0.05 mL portion of hydrosilylation catalyst (a solution of platinum-olefin complex in toluene) was added to a solution of R7T8OSi(Me2)H, (R=cyclohexyl) (11.0 g, 10.2 mmol, 1eq) and diallylbisphenol A (12.6 g, 41 mmol, 4eq) in tetrahydrofuran (110 mL) contained in a thick walled glass reaction vessel. The reaction mixture was heated to 70° C. for 72 h. After this time the tetrahydrofuran solvent was removed to give a viscous, semisolid residue. Extraction of the residue with acetonitrile gave a white solid which was collected by vacuum filtration and dried to provide 13.6 g (96% of theory) of the mono-POSS bisphenol A as a pale yellow solid. The product was mono-allyl, mono-dimethylsiloxypropyl hepatcyclohexyloctasilsesquioxane bisphenol A (or monoPOSS-monoallyl-bisphenol A) (or R37T8 (R2 -R4)1) or CH2 =CHCH2 (HO)C6H3C(CH3)2C6H3 (OH)(CH2)3Si(CH3)2OSi8O12 (c--C6H11)7. This is a new chemical compound and an example of formula 4 (#4).
