Manganese-catalysed dehydrogenative oxidation of glycerol to lactic acid

Abstract: Herein, we reported a well-defined pincer manganese complex supported by PNP ligands for the conversion of glycerol to sodium lactate with dihydrogen liberation. The sodium lactate could be obtained in...

“…To further prove the integrity of catalyst 1 , the catalytic reaction between β‐naphthol and benzyl alcohol was performed under standard conditions for 24 h. The resulting reaction mixture was subjected to 31 P NMR analysis, which revealed the presence of a characteristic signal at δ 53.0 ppm, which corresponds to the 31 P NMR of catalyst 1 [18] (see Supporting Information), and other signals at δ 54.0 and 54.5 ppm, which represent the intermediates formed from catalyst 1 during catalysis. Notably, no 31 P NMR signal for the free ligand ( δ −20.90 ppm) was observed [19] . These observations clearly rule out the decomposition of the catalyst, involvement of any nanoparticle formation, and heterogeneous pathway.…”

“…Recently, Fu have shown high reactivity of a Mn pincer complex which yielded 96 % yield of LA with 96 % selectivity. [21] To the best of our knowledge there are no other reports on the transformation of glycerol to LA using catalysts based on readily available, inexpensive 3d-transition base metals. Encouraged by our recent success on the use of simple base metal salts [22] including cobaltous chloride (CoCl 2 ) [22b,c] and their corresponding pincer complexes [22b] for the dehydrogenative transformation of alcohols, we envisaged the use of CoCl 2 as catalyst for the reforming of glycerol.…”

“…With an objective to move away from precious metal based catalysts, there have been many attempts recently to use catalysts based on earth‐abundant base metals. Recently, Fu have shown high reactivity of a Mn pincer complex which yielded 96 % yield of LA with 96 % selectivity [21] …”

“…Biomass is an abundant and renewable carbon resource, and the conversion of biomass to produce fuels and valuable chemicals is promising for sustainable development and arouses great attention. [1][2][3][4][5][6] Photocatalysis has recently been recognized as an efficient and feasible technology for biomass valorization under mild conditions, [7][8][9][10][11][12][13][14][15][16][17][18][19] owing to unique reaction mechanisms induced by photogenerated electrons and holes. 20,21 Selectivity control is one of the most important issues in the valorization of biomass.…”
