Olefin Metathesis in Green Organic Solvents and without Solvent

Unveiling the hyperbolic thermal behaviour of poly(p-phenylene alkylene)s

“…Organic carbonates (most commonly dimethyl carbonate) have been used as solvents for metathesis reactions, 18 and are almost as effective as the most common metathesis solvent, methylene chloride. 19 However, to the best of our knowledge, no ADMET reactions in organic carbonates have been reported previously. Dibenzyl carbonate (DBC) was selected for its high boiling temperature (180-190 °C at 2 mmHg), and aromatic content.…”

Ruthenium Complexes Featuring Unsymmetrical N‐Heterocyclic Carbene Ligands–Useful Olefin Metathesis Catalysts for Special Tasks

“…[54] Next, we found that this complex is stable under air in non-degassed common organic solvents (DCM, toluene), as well as in so-called "green solvents" [55] such as 2-MeTHF or dimethyl carbonate (DMC) usually leading to very good results in a range of metathesis reactions. [56] What is more, high selectivity of complex Ru52 has been demonstrated in ethenolysis of ethyl oleate (27) and in a set of self-CM reactions of various terminal olefins (Scheme 10).…”

Profluorescent substrates for the screening of olefin metathesis catalysts

“…Since its discovery in the 1950s, olefin metathesis has developed into one of the most powerful catalytic reactions both in research as well as in industrial applications [ 1 – 3 ]. This is mostly due to its excellent chemoselectivity, tolerance of many functional groups and its atom economy [ 4 ]. Chemists treasure its extraordinary versatility.…”
