✦ Synopsis

New synthetic methods for the preparation of z-or E-1,3-dienes are described.

Despite the availability of many reagents for the car-bony1 olefination reactions, there still exists a need for new method, especially for the stereoselective route to conjugated polyenes under mild conditions.

1 Herein we disclose the results of our new procedure involving (diphenylphosphino)allyltitanium reagent 2,3 which was prompted by our earlier success with (alkylthio)allyltitanium reagent.

Reaction of alkynes with ICI and an iodide source results in the stereoselective formation of diiodoalkenes in moderate to high yield. At r.t., the reaction is stereospecific, resulting in the formation of E-diiodoalkenes, however lowering the temperature mad using a more soluble iodide som'ee resul
