  1. 11. Bridging McMurry and Wittig in One-Pot : Olefins from Stereoselective, Reductive Couplings of Two Aldehydes via Phosphaalkenes

    Author : Juri Mai; Sascha Ott; Christian Müller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbonyl olefination; reductive aldehyde coupling; stereoselective; organophosphorus; phosphaalkene; phosphanylphosphonate; Wittig; Horner-Wittig; Horner-Wadsworth-Emmons; McMurry; Kemi; Chemistry;

    Abstract : The formation of C=C bonds is of great importance for fundamental and industrial synthetic organic chemistry. There are many different methodologies for the construction of C=C bonds in the literature, but currently only the McMurry reaction allows the reductive coupling of two carbonyl compounds to form alkenes.
