反応手順
The propargyl ester of 2-norborn-5-ene carboxylic acid was prepared by Diels-Alder reaction of propargyl acrylate and cyclopentadiene at ambient temperature. Dimethylchlorosilane (56.4g) was added portionwise to 100 grams of this norbornene carboxylate ester and 0.16 g Karstedt catalyst under nitrogen at 70° C. After exotherming to 80° C., the mixture was stirred for 3 hours at 70° C., stripped under light vacuum and then distilled. The product, ##STR13## (84% purity by GC), distilled at 100°-105° C. at 0.07 mm.
