Low stereoselectivity observed in the reaction of trans-mesylate 6 could be connected with the higher rate of allylic isomerization of (Z)-allyl bromide 4a in comparison with (E)-allyl bromide 3a due to steric interactions.

1H NMR spectroscopic data, product 9d contained inseparable admixtures of isomeric methylene compound (2-3%) along with diene hydrocarbon (2-3%). The latter were probably formed from the corresponding secondary allyl halide as a result of reductive dehalogenation and hydrodehalogenation reactions.
