Construction Kit for the Solvent Selection in Homogeneous Catalyzed ReactionsChoosing the right solvent for chemical syntheses is often the base for a successful large-scale implementation. Especially in homogeneous transition metal catalyzed reactions, the solvent can be the limiting factor in issues of catalyst recycling and product separation. This review presents possible solvent types for chemical synthesis and which tools can be used to select a suitable one. A view at new solvents will be taken, possible concepts of catalyst recycling will be explained and the concept of the green solvents will be discussed.

“…In particular, the findings that dimethyl carbonate was a suitable solvent for olefin metathesis transformations [16] prompted us to investigate the potential of temperature-dependent multicomponent solvent (TMS) systems using dialkyl carbonates as the polar phase. Since the first reports on thermomorphic catalysts by Bergbreiter in 1998 [17] and on temperature-dependent multicomponent solvent systems by Behr in 1999 [18], TMS systems have proven their interest and potential in a broad range of homogeneously catalyzed transformations [19][20][21][22][23][24][25].…”

International audienceHomogeneous catalysis is a major actor of modern chemistry with a growing impact on clean and sustainable chemical processes. However, for many industrial applications of homogeneously catalyzed reactions, an easy separation and recovery of the catalyst should be guaranteed. Temperature-dependent multicomponent solvent (TMS) systems have been evaluated in ruthenium catalyzed olefin metathesis transformations. Propylene carbonate was found a suitable solvent for the ruthenium catalyzed ring-closing and cross-metathesis transformations of a variety of substrates including renewable fatty esters. The potential of a TMS system consisting of propylene carbonate/ethyl acetate/cyclohexane was then evaluated in the cross-metathesis of the renewable methyl 10-undecenoate with methyl acrylate and acrylonitrile

“…So we tried to design a reusable catalytic system based upon temperature-dependency. Some methods have been explored for the recovery and reuse of the catalyst by controlling temperature such as the temperature-dependent multi-component solvent systems [23] and the protocols based on temperature-dependent solubilities of fluorous compounds [24]. Here, we first report the use of a polyoxometalate anion combined with dioctadecyl dimethyl ammonium ion, [(C 18 H 37 ) 2 (CH 3 ) 2 N] 7 [PW 11 O 39 ], for olefin epoxidation in a biphasic mixture of aqueous H 2 O 2 and ethyl acetate as a temperature-controlled catalytic system.…”
