Rhodium complexes containing sulfur and use as catalysts

Rhodium complexes containing sulfur and use as catalysts. Chandra, Grish (Dow Corning Ltd., Engl.). Brit. GB 1448826 8 Sep 1976, 4 pp. (English). (United Kingdom). CODEN: BRXXAA. CLASS: IC: C07F015-00. APPLICATION: GB 73-5962 7 Feb 1973. DOCUMENT TYPE: Patent CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 67 Four RhCl3 complexes useful as hydrosilylation catalysts were manufd. by treatment of RhCl3.3H2O with a S-contg. silane. Refluxing 1.31 g RhCl3.3H2O and 2.32 g EtSCH2SiMe3 6 hr in MeOH gave 2.5 g RhCl3(EtSCH2SiMe3)3(I). Five .mu.l. of a 3.26% soln. in PhMe of I, 0.55 g (Me3SiO)2SiMeH, and 0.43 g Me3SiOSiMe2(CH:CH2) were heated 10 min at 80. 54253-65-5 is just another one chemical used in this study.degree. giving 92% (Me3SiO)2SiMe(CH2)2SiMe2OSiMe3. .

All Rights Reserved. Transparent, UV- and thermal discoloration-resistant resin compositions for sealing optical elements.Several substances are used for example 5356-85-4 and 126503-69-3 which are their cas registry numbers. Nishida, Hirofumi (Nagase Chemtex Corp., Japan). Jpn. Kokai Tokkyo Koho JP 2007031619 A 8 Feb 2007, 14pp. (Japanese). (Japan). CODEN: JKXXAF. APPLICATION: JP 2005-219518 28 Jul 2005. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 29, 73 Title compns. comprise 31 liq. cage-like silsesquioxanes selected from (R1SiO3/2)a-n(X1SiO3/2)n (R1 = C2-12 aliph. unsatd. hydrocarbyl, silyloxy having aliph. unsatd. bond not having H-Si bond; X1 = org. group not having H-Si bond nor aliph. unsatd. bond; X1 1 H; a = 6-14 even no.; a > n 3 1) and (R2SiO3/2)a-n(X2SiO3/2)n (R2 = H, org. group having H-Si bond not having aliph. unsatd. bond; X2 = org. group not having H-Si bond nor aliph. unsatd. bond; X2 1 H; a = 6-14 even no.; a > n 3 1). Thus, 5 mmol octakis(vinyldimethylsiloxy)octasilsesquioxane was treated with 15 mmol heptamethyltrisiloxane in hexane in the presence of Pt catalyst (SIP 6831.2; 2.3% xylene soln. of divinyltetramethyldisiloxane-Pt complex) to give a liq. silsesquioxane deriv. (SQ-1), sep., 5 mmol octakis(dimethylsiloxy)octasilsesquioxane was treated with 25 mmol 1-hexene in hexane in the presence of SIP 6831.2 to give another liq. silsesquioxane deriv. (SQ-2). SQ-1 100, SQ-2 100, and SIP 6831.2 0.087 part were blended, poured in a mold, and cured at 120° for 2 h to give a test piece showing 350-nm transmittance 92% initially, 90 after 100 h UV exposure, and 72 after 100 h heating to 150°. .
