Hydrogenation of nitro compounds on nickel membranes: Hydrogenation of nitro compounds on nickel membranes. Sokol'skii, D. V.; Nogerbekov, B. Yu.; Gudeleva, N. N.; Mustafina, R. G. (Inst. Org. Katal. Elektrokhim., Alma-Ata, USSR). Zh. Fiz. Khim., 59(3), 609-12 (Russian) 1985. CODEN: ZFKHA9. ISSN: 0044-4537. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 25 The hydrogenation was studied of Na p-nitrophenolate [824-78-2] on a Ni membrane in an alk. soln. The dependence is shown of the yield of Na p-aminophenolate [15267-98-8] on the membrane potential, the intensity of the polarizing current, and the temp.

CLASS: IC: A61K031-70; C07H015-22. NCL: 424180000. APPLICATION: US 82-436208 25 Oct 1982. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 1, 33 Bis (or tris)[4-O-monohexosoxy]arylene sulfates and their cation salts are prepd. for pharmaceuticals to modulate complement activity in body fluids. Reaction of acetobromoglucose [572-09-8] and 4-O2NC6H4ONa [824-78-2] gave 4-nitrophenyl (2,3,4,6-tetra-O-acetyl)-b-D-glucopyranoside [5987-78-0] which was hydrogenated to give the 4-aminophenyl deriv. [42011-36-9]. This was treated with 1,3,5-benzenetrisulfonyl chloride [21538-06-7] to give I (X = Ac) [90735-15-2] which was deacetylated to I (X = H) [90735-16-3] and then converted to I (X = SO3NEt3) [90735-17-4] with Et3N-SO3 and then to I (X = SONa) [90735-19-6] with NaOAc. Pharmaceuticals were prepd. contg. these derivs. I (X = SO3Na) possesses high complement modulating activity in a test, measuring the ability of activated human C1 to destroy fluid phase human C2 in the presence of C4 and appropriate dilns. of the test compd.
