Embodiment
[0088] The following examples are used to describe the present invention in detail, but not to limit the scope of the present invention.
Synthetic example 1
[0090] Add 411.2 g (F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH=CH 2 ), 286.13 g of 1,3-bis(trifluoromethyl)benzene and 110.47 g of trichlorosilane. The contents were heated to 60° C. before adding 0.045 g of Pt metal complexed with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane over 3.7 hours. Keep the contents at 60 °C for an additional 30 min to make F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH 2 CH 2 SiCl 3 . Residual trichlorosilane and solvent were removed from the reaction mixture in vacuo before adding 156.5 g trimethyl orthoformate and 1.8 g methanol. The contents of the flask were kept at 60°C overnight to promote methoxylation of the chlorosilanes. After 14 hours an additional 5.2 g of methanol was added and the temperature was maintained for 3 hours. Add 2.5 g of activated carbon. Excess reagents were removed under vacuum. The product was filtered through a bed of diatomaceous earth (Celite) filter aid on ...
Synthetic example 2
[0092] To a 25 mL two-necked flask equipped with a magnetic stir bar, reflux condenser, temperature control and headspace purged with dry nitrogen was added 7.52 g (F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH=CH 2 ), 12.02 g of 1,3-bis(trifluoromethyl)benzene and 3.91 g of trimethoxysilane. Slowly add 1.4×10 over 16 hours -3 Before g Pt metal complexed with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane, the contents were heated to 100 °C. After two more hours, excess reagent was removed under vacuum. Product F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH 2 CH 2 Si(OMe) 3 Separated as flask residue, mixed with charcoal and filtered. IR and NMR spectroscopic analysis revealed no starting CH 2 =CHCH 2 The O functional group remains.
