Tetracarboxamides and tetrakis(2-ketocarboxamides) of resorcinarene-based cavitands have been synthesised in palladium-catalysed aminocarbonylation of the corresponding tetraiodocavitand. In this way, deepened cavitands with the same functionalities at the upper rim were obtained even in the simultaneous application of two primary amines as N-nucleophiles. The influence of base additives on the unexpectedly high chemoselectivity towards tetra-functionalised products, i.e. tetrakis(2-ketocarboxamides) and tetracarboxamides, has been investigated in details.

碱性添加剂对钯催化的氨基羰基化反应选择性的影响：空泡骨架的高度选择性官能化

基于间苯二甲烯的空洞分子的四羧酰胺和四（2-酮羧酰胺）已通过钯催化相应的四碘多取代基的氨基羰基化反应合成。以这种方式，即使在同时施用两种伯胺作为N-亲核试剂时，也获得了在上边缘具有相同功能的加深的空洞体。碱性添加剂对四官能化产物（即）的出乎意料的高化学选择性的影响。已经详细研究了四（2-酮甲酰胺）和四甲酰胺。
