α,α′-Bis(substituted-benzylidene)cycloalkanones were synthesized via a solvent-free cross-aldol condensation of aromatic aldehydes with cycloalkanones in the presence of a catalytic amount 1-methyl-3(2-(sulfooxy)ethyl)-1H-imidazol-3-ium chloride at room temperature with excellent yields. The screening for optical properties indicated that the size of cycloalkanone has an influence on the fluorescence
在催化量的 1-甲基-3(2-(磺氧基)乙基)-1H 存在下,通过芳香醛与环烷酮的无溶剂交叉羟醛缩合反应合成了 α,α'-双(取代亚苄基)环烷酮-咪唑-3-氯化鎓在室温下以优异的收率。光学性质的筛选表明,环烷酮的大小对产物的荧光发射有影响。来自环己酮的产物比来自环戊酮的产物具有更强的荧光发射。
