1517559 Unsaturated silanes having other functional groups RHONE POULENC INDUSTRIES 30 Sept 1975 [1 Oct 1974 11 Feb 1975] 40057/75 Heading C3S Novel silanes have the formula wherein each R is a C2-10 ethylenic radical; each R<1> is an alkyl, haloalkyl, cyanoalkyl, aryl or haloaryl radical; R<2> is a C1-4 alkylene or alkylidene; X is -O-, -S-, -NR<5>-, -O-CO-, -S-CO-, -O-CS-, -S-CS (R<5> being H or C1-4 alkyl); G is a C1-30 organic radical of valency m + 1; each Y is -NH2, -CONH2, -CSNH2, -CH2NH2, -NO2, -NCO, -NH-CO-CH2, -NH-CO-OR<3>, -COOH, -COONa, -COOK, -COOLi, -COOR<3>, -O-CO-R<3>, -COCl, -CS-SR<3>, -O-CS-R<3>, -S-CS-R<3>, -S-CO-R<3>, -SH, -SR<3>, -OH, -OR<3>, -CHO, -COR<3>, or 2 Y's together may be -CO-NR<4>-CO- (R<3> being C1-4 alkyl and R<4> H or C1-4 alkyl); m is 1, 2 or 3 and n is 1, 2 or 3. They may be prepared by reaction of the chloride with a compound Z-X-GYm, where Z is H or an alkali metal or a tertiary ammonium group. In the examples the silane ViMe2Si- CH2Cl (CH2=CHCH3-SiMe-CH2Cl in Example 5, Vi2MeSiCH2Cl in Example 9) is added to N-methylpyrrolidone solution of (a) (Example 1, the product being reduced to the amine with SnCl2 in Example 7, and the amine phosgenated in Example 8); (b) (Examples 3, 5 and 9, the ester produced being saponified in Examples 3 and 10, and the acid then converted with SOCl2 to the acid chloride in Examples 4 and 10); (c) in place of Et3N (Example 2); or (d) NaS-CH2-COOEt (Example 6). |
