“…In the presence of salicylic acid, the conversion and selectivity were similar to those obtained when Mn was not added. This result might be explained by the possible formation of complexes of manganese–salicylic acid (Lal et al., 2006), making manganese ions unavailable to participate in the epoxidation reaction.…”

The system hydrogen peroxide/sodium bicarbonate/manganese sulfate was used for the first time to epoxidize cyclopentene. Effects of parameters such as type and amount of solvent, ratio of hydrogen peroxide and manganese sulfate to cyclopentene, presence of additives, and reaction time and temperature on the selectivity to cyclopentene oxide were evaluated. Gas chromatography was used to quantify residual cyclopentene and produced cyclopentene oxide using the internal standard method. Type and amount of solvent, addition method, and temperature were important factors to increase the selectivity to cyclopentene oxide. Unlike previous reports on epoxidation of different substrates, additives like sodium acetate and salicylic acid did not improve the selectivity to cyclopentene oxide. One time, single-step addition of hydrogen peroxide/sodium bicarbonate to the solution of cyclopentene/solvent/manganese

“…The appearance of a band at around 1651 to 1546 cm -1 bond is attributed to mas(COO) and ms(COO), respectively. The band observed at 1349 cm -1 is attributed to ms(COO) vibration of carboxylate function [7]. The compound shows a split strong band in the region 3500-3300 cm -1 .…”

We report on the applicability of an easy and general synthesis procedure for the formation of Ce(IV)-MOFs. Cerium-based metal-organic frame (Ce-MOF) was successfully synthesized by a simple, cost-effective and green route. Highly homogeneous topology, nano-sized crystals, stable oxidation states Ce(III) and Ce(IV) at room temperature, significant surface area and thermal stability up to 320°C are the notable properties achieved by Ce-MOF. Electron transferability of the cerium electrode was used for the detection of methylene blue (MB) analyte in acidic buffer solution. Also the effect of different pH buffer solutions on electrode response has been studied. Photocatalytic performance of nano-Ce-MOF was studied on the degradation of MB analyte under visible light.

“…[4][5][6][7][8][9][10][11][12][13][14][15] The crystal structures, thermal, spectral, and magnesium properties of some nitrosalicylic acid complexes have been investigated. [16][17][18][19][20][21] Georges Morgant reported the low-temperature(100 K) crystal structures of pentaaqua (5-nitrosalicylate) complexes of magnesium(II), zinc(II), cobalt(II), and nickel(II). [2] However, we obtained a four nuclear Cu(II) and a binuclear Co(II) complexes with 5-(NO 2 )sal at normal temperature (298 K).…”

Two novel complexes, {Cu 2 [5-(NO 2 )sal] 2 (DMF) 4 } 2 (1) and{Co )sal] (H 2 O) 3 } 2 (2), have been prepared and characterized by elemental analysis, IR spectrum, and X-ray single-crystal diffraction. Complex 1 is a four nuclear Cu(II) complex and belongs to monoclinic system with space group C 2/c, a = 23.541 (2) Å, b = 14.8150(12) Å, c = 22.459(2) Å, β = 104.361(2) • , V = 7588.0(12) Å 3 , D c = 1.368 Mg/m 3 , Z = 4, F(000) = 3216, R 1 = 0.0826, wR 2 = 0.2212 [I>2σ (I)] Every Cu(II) atom is six-coordinated by three O atoms from two 5-(NO 2 )sal and two O atoms from two DMF and one bridged O atom. The distance of Cu···Cu are 4.5027(14), 5.817(2), and 5.526(2) Å. Complex 2 is a dinuclear Co(II) complex and belongs to monoclinic system with space group P 2 1 /c, a = 10.9003(9) Å, b = 13.6938(15) Å, c = 6.6781(5) Å, β = 91.223(1) • , V = 996.59(16) Å 3 , D c = 1.748 Mg/m 3 , Z = 2, F(000) = 596, R 1 = 0.1058, wR 2 = 0.3098 [I>2σ (I)] Every Co(II) atom is sixcoordinated by two O atoms from one 5-(NO 2 )sal and three O atoms from three coordinated water and one bridged O atom, and the distance of Co···Co is 3.191(3) Å. Two complexes have been screened for antibacterial activities by the agar-diffusion method and showed good effects against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis. (5-(NO 2 )sal = 5-nitrosalicylate anion, DMF = N, N-dimethylformamide).
