実験手順
A 50 mL round bottom flask equipped with a magnetic stirring bar and an addition funnel was charged with 7.7 g of 98% (3-hydroxypropyl)heptamethylcyclotetrasiloxane (22 mmoles) and 2.3 g of triethylamine (23 mmoles). The mixture was stirred and 15.0 g of 97% perfluoro-2,5,8-trimethyl-3,6,9-trioxadodecanoyl fluoride (21.9 mmoles) was added dropwise. After complete addition of the acid fluoride a gas chromatographic analysis indicated that essentially all of the acid fluoride and most of the cyclosiloxane were consumed with predominately the formation of one product. A 25 mL portion of dilute hydrochloric acid was added to the flask and the two phase mixture was transferred into a separatory funnel and the aqueous layer separated from the siloxane layer. The siloxane layer was washed with two 25 mL portions of water and the siloxane layer was transferred into a 50 mL round bottom flask and distilled at 110° C. and 0.3 mm Hg to yield a fraction of 14.7 g (66% yield) of 97% [3-(perfluoro-2,5,8-trimethyl-3,6,9-trioxadodecanoyl)oxypropyl]heptamethylcyclotetrasiloxane (14.3 mmoles), which corresponds to formula (I) wherein m is 1, n is 3, X is OC(O), and RF is given by formula (II) wherein p is 3, or more specifically as shown in formula (VII) below wherein p is 3. The product was analyzed by spectroscopy with the following results: 1H NMR 400 MHz, CDCl3 : d 0.1 (s 21 H), 0.6 (t 2 H), 1.8 (p 2 H), 4.4 (m 2 H); 19F NMR 376 MHz, CDCl3 : d -81 (CF3), -82 (CF3), -83 (CF3), -85 (CF3), -130 (CF2), -132 (CF2), -144 (CF); IR (neat liquid on NaCl): cm-1 : 2970 (m), 1780 (s), 1245 (vs), 1200 (s), 1145 (s), 1070 (vs), 995 (s), 970 (s), 810 (vs), 750 (m). ##STR8##
