Comparative experiment 6 to The reacted product 13 was performed by direct amino group substitution of tetraethoxy silane not via Grignard reagent. Namely, a 200 mL-volume flask, equipped with an agitating blade and a soxhlet extractor loaded with a monocular shive 4A-stuffed cylindrical paper filter, was employed, of which inside was substituted for nitrogen using a vacuum pump. Then, 83.3 g (0.40 mol) of tetraethoxysilane and 73.1 g (1.0 mol) of diethylamine were fed into the flask, and heated and revolved for 8 hours. Analysis of the resultant reacted solution by gas chromatography confirmed no target amino-substituted product but tetraethoxysilane of the starting substance only.
