APPLICATION: JP 2005-231311 12 Jul 2005. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 35, 63 Title compds. have structure AXNCHAr(CH2)nSiX1X2X3 [A, X = H, (substituted) C1-18 aliph. hydrocarbyl, (meth)acryloyl, etc.; Ar = aryl, alkoxycarbonyl, silyl, etc.; X1, X2, X3 = Me, Me3SiO, organosiloxy with ￡18 Si atom; n = 3-10]. Thus, dilithiation of N-phenylmethylbenzenecarbothioamide with n-BuLi in THF followed by reaction with 1-chloro-3-tris(trimethylsiloxy)silylpropane at 0° gave 84% compd. I, which was reduced with LiAlH4 in THF, and reacted with glycidyl methacrylate in the presence of Ca(OTf)2 in MeCN to give a mixt. of II and III in 43% yield. A compn. contg.In this experiment, several chemicals are used like 106-91-2 and 18077-31-1 II and AIBN was poured into a molding jig made of glass plates, a nylon sheet, and a silicone spacer, and heated to give a transparent film with thickness 0.2 mm. .
