Duffaut, N. published the artcilePreparation of some organosilicon compounds derived from ω-undecylenic alcohol, Recommanded Product: Triphenyl(pyridin-1-ium-1-yl)borate, the publication is Revue Francaise des Corps Gras (1957), 69-73, database is CAplus.
Reduction of Me 10-undecenoate gave the corresponding alc. which with SOCl2 in presence of PhNMe2 gave 80% Cl(CH2)9CH:CH2 (I). I added HSiCl3 quantitatively to give Cl(CH2)11SiCl3 (II), b16 189°, nD20 1.4688, d20 1.1204. With C6H6 and AlCl3 II furnishes 1-phenyl-11-trichlorosilylundecane, b16 216-18°, nD20 1.4955 d20 1.0788, and further, by methylation, 1-phenyl-11-trimethylsilylundecane, b3 176-7, nD20 1.4822, d20 0.8618, ν 698 and 759 cm.-1 II in ether gave with MeOH 1-chloro-11-trimethoxysilylundecane (III), b16 187°, nD20 1.4426, d20 0.9855. The Br analog (IV) was obtained, b16 196°, nD20 1.4559, d20 1.1192. III and IV gave very small amounts of amine by replacing the halogen by NEt2. From I Me3Si(CH2)9CH: CH2 (V) was prepared, b16 131-2°, nD20 1.4417, d20 0.8021, which with Cl3CCO2Et gave about 30% addition product, C18H35O2Cl3Si, b2.5 215-16°, nD20 1.4700, d20 1.0521.
