In one aspect, the invention provides a method for synthesizing a fatty olefin derivative. The method includes: a) contacting an olefin according to Formula I
with a metathesis reaction partner according to Formula IIb
in the presence of a metathesis catalyst under conditions sufficient to form a metathesis product according to Formula IIIb:
and
b) converting the metathesis product to the fatty olefin derivative. Each R
1
is independently selected from H, C
1-18
alkyl, and C
2-18
alkenyl; R
2b
is C
1-8
alkyl; subscript y is an integer ranging from 0 to 17; and subscript z is an integer ranging from 0 to 17. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is a pheromone. Pheromone compositions and methods of using them are also described.
Provided is a highly efficient method for the production of aldehydes and ketones, which is inexpensive, exhibits high reactivity, and is capable of easy separation of byproduct after the reaction. More particularly, there is provided a method for producing an aldehyde or a ketone, comprising at least an oxidation step of oxidizing a primary alcohol or a secondary alcohol in the presence of a polymeric carbodiimide represented by the following formula (1) and having a weight-average molecular weight of 300 to 5000, and a sulfoxide compound, together with an acid and a base, or together with a salt of the acid and the base.
The present disclosure provides pheromone compositions. In some aspects, the compositions taught herein comprise a pheromone chemically corresponding to the pheromone naturally produced by a given insect, along with at least one positional isomer of said pheromone. In various aspects, pheromone compositions of the present disclosure are able to modulate the response of the insect based on the ratio of natural pheromone to its positional isomer.
