Abstract
Methods of carrying out metathesis reactions of natural oil-derived polyenes (e.g., dienes and trienes), including functionalized polyenes, are generally disclosed herein. In some embodiments, the dienes or trienes contain a terminal carbon-carbon double bond, and the metathesis reaction is selective toward reaction of the terminal carbon-carbon double bonds in the polyene. Compounds made by such methods are also generally disclosed herein.
Claims20
A method for forming a dimer by olefin metathesis, the method comprising:
- providing a reactant composition comprising a compound of formula (Ia):
- and a compound of formula (Ib):
- and
- reacting the compound of formula (Ia) with the compound of formula (Ib) in the presence of a metathesis catalyst to form a product composition comprising a compound of formula (II):
- wherein:
- Z1 is —(CH2)7—, or —CH2—CH═CH—(CH2)4—;
- R1 is an organic group;
- and
- R2 is a hydrogen atom or an organic group;
- provided that the compound of formula (Ia) is derived from a natural oil.
