Abstract
A method of carrying out a metathesis reaction includes the combination of at least one alkene or non conjugated diene with a Ruthenium-based catalyst with an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture and heating the reaction mixture to a temperature of 100° C. or greater. The reaction can be an ADMET, ROMP, a metathesis ring-closure or an olefin exchange reaction.
Claims19
A method of metathesis polymerization, comprising:
- forming a polymerization mixture by combining
- a Ruthenium-based catalyst comprising a cyclic(alkyl)(amino) carbene ligand, and
- one or more selected from
- at least one cyclic monomer comprising an alkene,
- at least one linear monomer comprising an α,ω-dieneyl-monomer,
- and combinations thereof;
- heating the polymerization mixture to a temperature of 100° C. or greater.
4 more elements
A method of metathesis ring-closure, comprising:
- combining at least one acyclic non-conjugated diene with a Ruthenium-based catalyst comprising an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture;
- and
- heating the reaction mixture to a temperature above 100° C.
A method of metathesis olefin exchange, comprising:
- combining at least one alkene with a Ruthenium-based catalyst comprising an cyclic(alkyl(amino)carbene ligand to form a reaction mixture;
- and
- heating the reaction mixture to a temperature above 100° C.
