In the case of C2H5SiHC12 not only ethyl difurfuryloxy silane but also ethyl tri- furfuryloxy silane were isolated. This indicattis that the reaction partially proceeds via the Si-H bond. Re-esterification of ethoxy silanes with furfuryl alcohol (method 6) is simpler from theexperimental point of view: R Si(OC H + (4-n) CH OH( R Si (OCH / N + (4-n)C H OH n 2 5 4-n ~O 2 n 2 ~,~ 4-n 2 5 In some cases, however, the reaction proceeds slowly and the separation of the main product is rendpred difficult by the impurities if the partially substituted esters. The best results could be obtained when using sodium furfurylate as a catalyst. The reactions were made in a distilling flask with dephlegmator in oil bath. For the production of trialkyl furfuryloxy silanes dehydrocondensation of hydride silanes with alcohols in the pre- sence of metallic sodium (Ref. 11: B. N. Dolgov, N. P. Kharitonov, 'A. G. Voronkov, ZhOKh, 2A, 1176, (1954)) was successfully employed (methode;,. Card S/197/61/000/007/002/002 Syntheses in the series of ...

Most of the furfuryloxy silanes are colorless liquids with a characteristic smell and turning yellow on standing. At temperatures of 1450C and higher, the furfuryloxy silanes distilled in the vacuum are yellowish. The furfuryloxy silanes are soluble in ether, ethanol, benzene, and toluene, and insoluble in water. On heating they are gradually polymerized while forming brown non- distillable, highly viscous substances. All frequencies characteristic of the disubstituted furans can be observed in the infrared spectrum (Table 2) There are 2 tables and 17 references: 8 Soviet-bloc and 9 non-Soviet-bloc. The three most important references to English-language publications read as follows: Ref. 15: A, Cross, S. Stevens, T. Watts, J. Appl. Chem., Card 3/ 7 Syntheses in the series of ...
