It is shown that the position of the double bond close to the hydrocarbon end of an aliphatic diene functionalized at C(1) can readily be determined by chemical ionization with NO+.Owing to the low abundance of the ions characteristic for the position of the other double bond, its localization may be difficult.Measurement of the chemical ionization (nitric oxide as reagent gas) spectra of the corresponding epoxides or collision activation studies can help.

The stereospecific reduction of EE 2-benzenesulfonyl-1,3-dienes to ZE 1,3-dienes with Grignard reagents under transition metal catalysis is described.Hydrogenolysis of the sulfonyl moiety of 2-benzenesulfonyl-1,4-dienes to ZE 1,4-dienes with sodium dithionite is reported.These techniques have been applied to the stereoselective synthesis of (7E, 9Z) dodecadienyl acetate 3d, (9Z, 11E) tetradecadienyl acetate 3e and (9Z, 12E) tetradecadienyl acetate, 6b.
