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.
