Immobilization of Ru(terpyridine)(2,6‐pyridinedicarboxylate) onto MCM‐41 and its catalysis in the oxidation of alcohols

Abstract: The ruthenium complex Ru(terpyridine)(2,6‐pyridinedicarboxylate) was successfully grafted onto MCM‐41 using a multi‐step grafting method. The immobilized ruthenium complex was characterized thoroughly using Fourier transform infrared, Raman, UV–visible diffuse reflectance and energy‐dispersive X‐ray spectroscopies, X‐ray diffraction, N2 adsorption, scanning electron microscopy, thermogravimetric analysis and inductively coupled plasma analysis. This immobilized ruthenium complex showed excellent performance in… Show more

“…Their remarkably high binding affinity towards most transition-metal ions and their chelation properties make terpyridine derivatives highly attractive building blocks for the construction of complex metallosupramolecular systems [5][6][7][8][9][10]. Coordination complexes with functionalized terpyridines are used in catalysis, [11][12][13] photochemistry, [14][15][16] medical chemistry [17][18][19] and dye sensitized solar cells. [20][21][22][23][24] Along this line, it seems interesting to develop an easy synthesis for such terpyridine derivatives.…”

“…The oligomer-Ru(terpy)(pydic) showed better performance than the organic polymer supported ruthenium complexes but poorer performance than the inorganic immobilized ruthenium complexes. 27,[40][41][42][43] The ruthenium content of the samples of the fresh catalyst and recovered one aer the h run was determined by ICP to be 12.7 wt% and 10.5 wt%, respectively. The ruthenium loss is approximately 17.3%.…”

“…To this end, some ruthenium complexes were supported on organic or inorganic supports and the immobilized complexes exhibited good recyclability in the oxidation of various alcohols to the corresponding ketones. 27,[40][41][42][43] Although promising results were obtained, the immobilization processes were tedious in some cases, and the immobilization of the complex generally led to decrease of its activity due to mass transfer resistance of the reactants in the matrix of the support. Very recently, we used a polymer with a tridentate 2,6-bis(benzimidazol-2-yl)pyridine (bbp) unit in combination with disodium pyridine-2,6dicarboxylate (pydic) coordinating with RuCl 3 to form a polymer-ruthenium complex poly-Ru(bbp)(pydic).…”

“…Therefore, we have been engaged in developing oxidation reactions catalyzed by ruthenium complexes. Several ruthenium complexes with 2,6‐pyridinedicarboxylate (dipic) have been found to be efficient in the oxidation of various substrates with molecular oxygen or tert ‐butyl hydroperoxide (TBHP) . A close–open equilibrium of an axial Ru─O bond of Ru(III) with dipic in solution was detected which was important in oxidation reactions.…”
