Related Products of 486-73-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 486-73-7, molcular formula is C10H7NO2, introducing its new discovery.
Reactions of the tin precursors, R2Sn(OMe)OSO2Me (R = n-Pr, n-Bu), with an equimolar quantity of 2-quinoline/4-methoxy-2-quinoline/1-isoquinoline carboxylic acid in acetonitrile proceed under mild conditions (rt,12-15 h) via selective Sn-OMe bond cleavage to afford the corresponding mixed-ligand diorganotin derivatives [R2Sn(O2CR?)-OSO2Me]2 [R? = C9H6N-2, R = n-Pr (1), n-Bu (2); R? = 4-OMe-C9H5N-2, R = n-Pr (3), n-Bu (4); R? = C 9H6N-1, R = n-Pr (5), n-Bu (6)]. These have been characterized by FAB mass, IR, and multinuclear (1H, 13C, 119Sn) NMR spectral data and X-ray crystallography (for 4 and 6). The molecular structure of 4 (C20H29NO6SSn, monoclinic, P21/n, a = 14.1(13) A, b = 16.7(18) A, c = 20.3(19) A, beta = 107(4) Z = 8) comprises distorted octahedral geometry around each tin atom by virtue of weakly bridging methanesulfonate [Sn(1A)-O(3B) = 3.010, Sn(1B)-O(3A) = 2.984 A] and {N,O} chelation of the carboxylate ligands. The spectral data of 1-4 suggest a similar structural motif in solution. The molecular structure of 6 (C38H 53N2O10S2Sn2, monoclinic, P21/c, a = 11.339(2) A, b = 14.806(3) A, c = 24.929(5) A, beta = 100.537(3), Z = 4) reveals varying bonding preferences with monomeric units being held together by a bridging methanesulfonate [Sn(2)-O(5) = 2.312(2), A] and a carboxylate group bonded to Sn(1) and Sn(2) atoms, respectively. Slow hydrolysis of compound 2 derived from 2-quinoline carboxylic acid in moist CH3CN affords the asymmetric distannoxane, [Bu2Sn(O2CC9H 6N-2)-O-Sn(OSO2Me)Bu]2 (7) (C 27H45-NO6SSn2, monoclinic, C2/c a = 21.152(3) A, b = 13.307(2) A, c = 26.060(4) A, beta = 110.02(10), Z = 8) featuring ladder type structural motif by virtue of unique mu2-coordination of covalently bonded oxygen atoms [0(6), 0(6)#1] of the methanesulfonate groups.
