ene–yne cross‐metathesis is performed with stoichiometric proportions of terminal olefins and alkynes. This is made possible by the continuous addition of the alkyne to the reaction mixture. The protocol allows the ene–yne cross‐metathesis reaction to be carried out with long‐chain terminal olefins and in a one‐pot fashion with internal olefins after shortening by ethenolysis. The efficient conversion
钌催化的烯-炔交叉复分解是按化学计量比例的末端烯烃和炔烃进行的。通过将炔烃连续添加到反应混合物中,这是可能的。该方案允许通过长链末端烯烃进行烯-炔交叉复分解反应,并通过乙烯分解缩短与内部烯烃的一锅法。使用这种技术,在温和的条件下,在碳酸二甲酯中,将生物资源中的可再生不饱和脂肪酸酯有效地转化为有价值的共轭1,3-二烯,以进行进一步转化。一种环保溶剂。
