Under these conditions, sulfonylated alkyl- or arylamines and various N-heterocycles, such as oxazolidinones or indoles, could be efficiently transformed into the corresponding&amp;nbsp;N-alkynyl derivatives. However, imidazoles gave addition products rather than coupling products. The reaction conditions proved compatible with a variety of functional and protecting groups. Such zeolitic catalysts can be recycled and reused at least five times without significant deactivation. Low catalyst loading could be used (4 mol%) and as low as&amp;nbsp;0.8 mol%&amp;nbsp;of this heterogeneous copper catalyst still gave good conversion and yields. &amp;nbsp; &amp;nbsp;</style></abstract></record></records></xml>
