para-Substituted salicyldialdehydes are versatile molecular building blocks for porous organic cages, fluorescent dyes, spirobenzopyrans, homooxacalixarenes, dinuclear metal complexes, macrocycles, and cryptands. To date, no procedures for the synthesis of para-aryl-substituted salicyldialdehydes have been reported, which would broaden the scope of the above-mentioned topics, especially in the field
对位取代的水杨二醛是用于多孔有机笼、荧光染料、螺苯并吡喃、高氧杂杯芳烃、双核金属配合物、大环化合物和穴状配体的通用分子构件。迄今为止,尚未报道合成对芳基取代的水杨二醛的方法,这将拓宽上述主题的范围,特别是在传感器和染料领域,因为芳香π系统可以扩大和吸收或荧光事件可以通过各种取代基进行微调。在此,报道了具有吸电子和供电子芳族单元的对芳基取代的水杨二醛的两种合成路线。
