Terminal selective metathesis of polyenes derived from natural oil

摘要

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.

1. 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.
