In the present work, a simple method for the synthesis of alkynyltellurides is described by the reactions of terminal alkynes with diorganyl ditellurides in the presence of a catalytic amount of K3PO4. In both substrates, it was possible to vary the aryl and alkyl groups, obtaining the products of interest in short reaction times and in yields ranging from 30 to 93%. This methodology, different from
在目前的工作中,描述了一种简单的合成炔基
碲化物的方法,该方法是在催化量的K 3 PO 4存在下,末端
炔烃与二有机基二
碲化物反应。在两种底物中,都可以改变芳基和烷基,从而以较短的反应时间和30%至93%的产率获得目标产物。该方法与文献中已经报道的方法不同,具有使用催化量的弱碱而不使用
金属催化剂的优点。
