The lanthanide(III) trifluoromethanesulfonate-catalyzed condensation of benzyl alcohols with primary and secondary alcohols is described. This reaction proceeds readily with benzyl alcohols that have an alkyl or aryl substituent at the α-, ortho-, or para-position using microwave radiation or heating. The intramolecular variant of this reaction leads to cyclic benzofurans.
三氟甲磺酸镧(III)催化苄醇与一、二级醇的缩合反应被报道。该反应在微波辐射下或加热下可顺利进行,苄醇在α位、邻位或对位带有烷基或芳基取代基。该反应的分子内变体则生成苯并呋喃。
