  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Numerous organic
    transformations are based on the use of stoichiometric amounts of phosphorus reagents.
    The formation of phosphane oxides from phosphanes is usually the thermodynamic
    driving force for these reactions. The stoichiometric amounts of phosphane oxide
    which are formed as by-products often significantly hamper the product purification.
    Organophosphorus catalysis based on P(III)/P(V) redox cycling aims to address
    these problems. Herein we present our recent advances in developing catalytic
    Wittig-type reactions. More specifically, we reported our results on catalytic
    Wittig reactions based on readily available Bu<jats:sub>3</jats:sub>P=O as pre-catalyst
    as well as the first microwave-assisted version of this reaction and the first
    enantioselective catalytic Wittig reaction utilizing chiral phosphane catalysts.
    Further developments led to the implementation of catalytic base-free Wittig reactions
    yielding highly functionalized alkylidene and arylidene succinates.</jats:p>"
