CeO2-supported Pt nanoparticle catalysts enabled the acceptorless dehydrogenative synthesis of 2-substituted quinazolines from 2-aminobenzylamine with aliphatic and benzyl primary alcohols or aldehydes with low catalyst loading, wide substrate scope and good catalyst reusability, demonstrating the first acceptor-free and additive-free catalytic system for this reaction.
CeO 2负载的Pt纳米颗粒催化剂能够由2-氨基苄胺与脂肪族和苄基伯醇或醛进行无受体脱氢合成,具有低催化剂载量,广泛的底物范围和良好的催化剂可重复使用性,证明了第一种无受体和添加剂的化合物此反应的无催化体系。
