Oezdemir, Ismail,Sahin, Neslihan,Cetinkaya, Bekir
, p. 205 - 209 (2007)
Six [RuCl2(1-alkylbenzimidazole)(p-cymene)] complexes have been prepared and the new compounds characterized by C, H, N analyses, 1H NMR, and 13C NMR. The reduction of ketones to alcohols via transfer hydrogenation was ach
New dipyridylamine ruthenium complexes for transfer hydrogenation of aryl ketones in water
Romain, Charles,Gaillard, Sylvain,Elmkaddem, Mohammed K.,Toupet, Loic,Fischmeister, Cedric,Thomas, Christophe M.,Renaud, Jean-Luc
, p. 1992 - 1995 (2010)
A new family of cationic organometallic chloro compounds of the type [(arene)Ru(N,N)(Cl)]+ containing N,N-chelating dipyridylamine ligands has been synthesized and isolated as the chloride salts, which are water soluble and stable to hydrolysis. The resulting mononuclear ruthenium complexes catalyze the transfer hydrogenation of aryl ketones in aqueous solution to give the corresponding alcohols with good conversion and interesting recyclability.

The first ruthenium complexes of bulky tris(triazolyl)borate (Ttz) ligands were synthesized, fully characterized, and studied as transfer hydrogenation catalysts. The structures of the complexes were (η6-arene)RuCl(N, N), where in each case N,N is a κ2-Ttz or bis(triazolyl)borate (Btz) ligand (arene = p-cymene (1, 3, 5, 6), benzene (2), C6Me 6 (4); N,N = TtzPh,Me* (1, 2), TtzMe,Me (3, 4), Ttz (5), Btz (6)). All but 5 were crystallographically characterized, and notably for 1 and 2 a rearranged ligand structure is observed (as indicated by an asterisk). These complexes were all effective catalysts for transfer hydrogenation of aryl ketones in isopropyl alcohol with base co-catalyst, with rates that were accelerated by moisture-free conditions. Complexes 1 and 2 are also effective catalysts for base-free transfer hydrogenation, and with 1 hydrogenation of several base-sensitive substrates was demonstrated. The ability of 1 to serve as a hydrogenation catalyst without base is attributed primarily to steric bulk, and a preliminary mechanism for formation of that active catalyst is proposed.
Mn(i) phosphine-amino-phosphinites: a highly modular class of pincer complexes for enantioselective transfer hydrogenation of aryl-alkyl ketones
Jayaprakash, Harikrishnan
supporting information, p. 14115 - 14119 (2021/10/25)
A series of Mn(i) catalysts with readily accessible and more π-accepting phosphine-amino-phosphinite (P′(O)N(H)P) pincer ligands have been explored for the asymmetric transfer hydrogenation of aryl-alkyl ketones which led to good to high enantioselectivities (up to 98%) compared to other reported Mn-based catalysts for such reactions. The easy tunability of the chiral backbone and the phosphine moieties makes P′(O)N(H)P an alternative ligand framework to the well-known PNP-type pincers.

Paragraph 0147-0157, (2021/12/07)
The invention relates to the technical field of organic synthesis, in particular to a ferrocene derivative metal organic complex and a preparation method and application thereof. The ferrocene derivative metal organic complex disclosed by the invention is shown I, contains a pincerlike ligand in the structure, and therefore has high stability and long service life. , The ferrocene derivative type metal organic complex has high catalytic activity, and only 0.001 μM % - 0.01 μM % is used, so that the chiral compound can be efficiently and rapidly prepared. The ferrocene derivative metal organic complex central metal is ruthenium, the economic cost is low, and the method has the prospect of industrial popularization.
