“…The catalyst displayed relatively high recyclability up to 10 times with no significant loss of activity and low levels of Ru leaching was reported. 41 Despite these efforts, very little attention has been focused on using soluble polymer bound alkylidene Ru complexes in ROMP to prepare products with lower Ru contamination. Moreover, ROMP is a robust method for synthesizing functionalized polymers, producing totally linear materials.…”

Equilibrium ring opening metathesis polymerization (ROMP) of strained cyclic olefins using a soluble supported second generation Ru complex has been investigated. Cycloolefin homoand copolymers are of great academic and industrial importance due to their interesting applications as packaging materials, adhesives in coatings and optoelectronics. The supported complex exhibits good chemical stability and was effective in ROMP of strained cyclic olefins. In addition, the complex is easily phase separated from the product resulting in lower residual ruthenium in the final polymer product compared with the homogeneous complex.

“…To the best of our knowledge, only few studies on ruthenium-catalyzed olefin metathesis transformation in TMS system and thermomorphic polymer supported catalysts have been reported [26][27][28]. Herein, we present our results on olefin metathesis transformations in TMS system employing propylene carbonate as the polar phase.…”

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

An imidazolium catalyst supported on thermomorphic polyethylene (PE) was prepared from 1methylimidazole and polyethylene iodide (PEÀ I). The catalyst was characterized by 1 H and 13 C NMR, SEC and MALDI-ToF mass spectrometry. Its catalytic activity was evaluated in the ring-opening of epoxides with carbon dioxide to give cyclic carbonates under solvent-free conditions. The catalyst proved to be active at low catalyst loading (down to 0.1 mol%) and allows the reaction to occur at low CO 2 pressure (1-5 bar) and moderate temperature (100°C). A range of terminal and internal epoxides was converted to the corresponding cyclic carbonates with high yields and selectivities. The recyclability of the catalyst was studied and no significant loss of activity was observed after 5 runs.
