Under solvent control: Benzyl thioethers were alkenylated in excellent yields with broad substrate scope and the selectivity (mono- vs. disubstituted product) was controlled by the solvent and ratio of reactants. Sequential alkenylation with two different alkenes was also carried out in a one-pot process. In addition, the thioether directing group was removed in a one-pot process with simultaneous hydrogenation of the double bond to give the toluene derivatives.
苄基硫醚能以优异的产率进行烯基化反应,底物范围广泛,且(单取代与双取代产物的)选择性可通过溶剂和反应物比例来控制。还能在一锅法中用两种不同的烯烃进行连续烯基化反应。此外,硫醚导向基团可在一锅法中被去除,同时双键氢化得到甲苯衍生物。
