The nickel-catalysed coupling of certain Grignard reagents with 6-alkyd-3,4dihydro-2H-pyrans is highly stereoselective and gives tri-substituted alkenes with retention of configuration. The method was app/ied to the synthesis of (E)-3-Acetoxy-7methyl-6-nonene, the aggregation phermone of the square-
