Procedure: FIG. 9 shows a synthesis of 9-tetradecenyl formate, in which 5-decene is cross-metathesized with 9-decenol in the presence of Grubbs' catalyst to produce 9-tetradecenol while 1-hexene is removed from the reaction under vacuum, and in which the metathesis product, 9-tetradecenol, is reacted with formyl acetate.

Procedure: In contrast to the “classical” ruthenium metathesis catalysts mentioned above, which react only with highly-strained olefins, alkylidenes 6 and 7 of Example 6 also promote the ROMP of less-strained monomers such as 1,5-cyclooctadiene, and are active in the metathesis of acyclic olefins in protic solvents. For example, 6 will dimerize 1-hexene in methanol to give 5-decene in 20% yield (Equation 3). In these systems, separation of catalyst from product is facilitated through addition of water to the reaction mixture. Olefins collected from the resulting two-phase system contain very low levels of detectable ruthenium.

Procedure: A process for preparing 9-tetradecenyl alcohol by reacting 1-hexene or 5-decene with 9-decenyl acetate in accordance with the method of claim 7 to obtain tetradecenyl acetate and then reacting the acetate with water to obtain said alcohol.
