Substituted azosilanes useful in rubber manufacture: Substituted azosilanes useful in rubber manufacture. Dawes, Keith; Rowley, Roger James (Malaysian Rubber Producers Research Assoc., Engl.). Ger. Offen. DE 2704506 11 Aug 1977, 42 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07F007-18. PRIORITY: GB 76-4802 6 Feb 1976. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) Section cross-reference(s): 29 The compds. RZ1CON:NCOZ2A [R = hydrocarbyl or A; A = (trialkoxysilyl)hydrocarbyl; Z1, Z2 = NH, O, methylene] are useful as couplers for SiO2-filled rubbers. Thus, adding 18 g p-H2NC6H4CH2CH2Si(OEt)3 [18418-80-9], 6.87 g Et3N, and 60 mL ligroine (b. 30-40.degree.) over 1.Several reagents such as 64185-92-8 is used here.5 h to 9.98 g PhOCOCl [1885-14-9] and 40 mL ligroine and stirring 30 min at room temp. gives 21.7 g PhOCONHC6H4CH2CH2Si(OEt)3 [64185-93-9]. Refluxing this compd. 20.7, Me3SiCl 7.60, and Et3N 7.1 g in PhMe 1.5 h, filtering, and refluxing with 5.3 g H2NNHCO2Et [4114-31-2] gives 7.60 g (EtO)3SiCH2CH2C6H4NHCONHNHCO2Et [64185-94-0], oxidized (9 g) with 4.45 g N-bromosuccinimide [128-08-5] and 1.98 g pyridine in 120 mL CH2Cl2 to give 8 g (EtO)3SiCH2CH2C6H4NHCON:NCO2Et (I) [64209-50-3]. Compounded natural rubber contg. 50 phr SiO2 (Hi-Sil 233) and 0.75 phr I has vulcanization time at 140.degree. 17 min, tensile strength 22.0 MPa, 300% modulus 6.73 MPa, and elongation 623%, as compared with 18, 15.6, 3.05, and 684, resp., in the absence o I, and 14, 29.9, 11.0, and 593, resp., with (MeO)3Si(CH2)3SH in place of I. .

Namikawa, Hiroyuki; Murakami, Teiichi; Hado, Masakatsu (Agency of Industrial Sciences and Technology, Japan). Jpn.In this study， 1885-14-9 and 139958-63-7 are also used. Kokai Tokkyo Koho JP 03264569 A2 25 Nov 1991 Heisei, 5 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C07D263-24. ICA: C07D498-04. APPLICATION: JP 90-61851 13 Mar 1990. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The title compd. (I), useful as intermediate for sphingolipids, is manufd. by treating D-glucosamine.HCl with Ph chloroformate to give N-phenoxycarbonyl-D-glucosamine (II), converting II to 2N,3O-carbonyl-D-glucosamine (III) by a strongly basic ion exchange resin, reducing and ring-contracting III to give 3-amino-2O,3N-carbonyl-3-deoxy-L-threose (IV), and introducing the olefin group to IV to give I. Thus, glucosamine.HCl was treated with Ph chloroformate to give 98% II, II was dissolved in MeOH and stirred first with a strongly basic ion exchange resin and then with a weakly acidic ion exchange resin and p-MeC6H4SO3H to give 43% III, III was reduced with NaBH4 and oxidized with NaIO4 to give 70% IV, and IV was treated with tetradecyltriphenylphosphonium bromide in THF in the presence of KOCMe3 to give 28% I. Treating 2,3,4,6-tetraacetylgalactosyl trichloroacetoimidate with I in CH2Cl2 in the presence of BF3.Et2O at room temp. gave 42% 2N,3O-carbonyl-D-threosphingosyl 2,3,4,6-tetraacetylgalactoside. .
