2-Alkenylphosphonates and PO-ylides derived thereof in trans selective Horner-Wittig olefination reactions

Allylic PO-ylides generated from dialkyl or diaryl 2-alkenylphosphonates by treatment with a strong base react with aldehydes to afford 1,3-dienes trans-selectively. The newly formed double bond typically exhibits Z/E ratios of 1:99. [on SciFinder (R)]
