An efficient and mild route for the formation sulfur or phosphor-substituted alkynes was herein demonstrated. The Mukaiyama reagent-mediated transformation started from easily-accessible substrates without carbon-carbon triple bonds, and the reaction proceeded under mild conditions (room temperature) in a one-pot manner, requiring for no transition metal-catalysts. The practical protocol featured for good functional groups tolerance (up to 41 examples) and high efficiency (up to 91% yields) towards alkynyl sulfones and alkynyl phosphonates at low cost.

Mukaiyama试剂促进在温和条件下的炔基砜和膦酸酯的无金属制备

本文证明了形成硫或磷取代的炔烃的有效且温和的途径。Mukaiyama试剂介导的转化从没有碳-碳三键的易于接近的底物开始，并且反应在温和条件下（室温）以一锅法进行，不需要过渡金属催化剂。该实用协议的特点是，以较低的成本对炔基砜和炔基膦酸酯具有良好的官能团耐受性（最多41个实例）和高效（最多91％的收率）。
