Abstract Under the protection of nitrogen, the use of THF as best solvent can increase the yield or stereoselectivity of the H 2 O 2 induced oxidation of Wittig reagents to give the corresponding dimerization products ( trans ‐alkenes) as the major or only product in better to good yields up to 98 %. This reaction can be expanded to the aryl system in the yield up to 94 % for homo‐coupled dimers or 58 % for cross coupled dimers. This result will expand the synthetic application scope of Wittig reagents and H 2 O 2 .
