Wittig-Homer reactions Knoevenagel reaction

Wit tig, Wittig-Homer, and Knoevenagel reactions These reactions can be carried out with A1203 or KF supported on A1203 without solvent, but addition of water catalyzes both Wittig and Wittig-Homer reactions. Under these conditions trimethylsulfonium iodide undergoes reaction to form epoxides (equation I). [Pg.15]

With some methylene active compounds (NCCH2PO(OEt)2) competition between Knoevenagel and Wittig-Homer reactions has been observed the ratio of Knoevenagel and Wittig-Homer products is dependent upon the reaction conditions. [Pg.353]

Olefinations (preparations of alkenes) by Knoevenagel and aldol condensations [43], and the Perkin reaction [44] have been complemented by Wittig [45] or Homer olefina-... [Pg.127]
