    Polymer-Supported Triazenes as Smart Reagents for the Alkylation of Carboxylic Acids
    (2012-11-09) Bernhard Erb; Jean-Philippe Kucma; Sandrine Mourey; Fritz Struber
    Starting from polystyrene, a simple four-step synthesis of polymersupported alkyltriazenes (alkyl Me, Et, benzyl) is described. With this synthesis, a loading capacity of 2.2 mmolg 1 can be reached. The most prominent application of these polymer-supportedreagents is the rapid, highly selective and high-yielding esterification of car

    Polymer-Supported Triazenes as Smart Reagents for the Alkylation of Carboxylic Acids
    (2012-11-21) Bernhard Erb; Jean-Philippe Kucma; Sandrine Mourey; Fritz Struber
    Starting from polystyrene, a simple four-step synthesis of polymersupported alkyltriazenes (alkyl Me, Et, benzyl) is described. With this synthesis, a loading capacity of 2.2 mmolg 1 can be reached. The most prominent application of these polymer-supported reagents is the rapid, highly selective and high-yielding esterification of carboxylic acids, which involves a simple .mix and filter off ç procedure at room temperature. If stored in a refrigerator, these reagents are stable for many months and they can be recycled several times
