Phenylseleno‐ and p ‐tolylsulfonyl substituted 1,3‐dienes were conveniently prepared with high stereoselectivity by the elimination reaction of phenylseleno‐ and p ‐tolylsulfonyl substituted allyl alcohols in the presence of BF 3 · Et 2 O in acetic anhydride. The products were characterized by 1 H NMR, MS, IR and elemental analysis. The single crystal structure of 2a was determined by X‐ray diffraction analysis.
