A new type triazole acetyl gold(III) was prepared and found to be an effective catalyst in Meyer–Schuster rearrangement of propargyl alcohols. The reactions proceeded well under much milder conditions to afford enones bearing a wide range of functional groups, thereby opening a new avenue for gold(III) catalysis. In addition, TriaAuCl2 catalyst was also effective on promotion of a-haloenones synthesis
制备了一种新型的三唑乙酰
金(III),发现它是炔
丙醇Meyer-Schuster重排的有效催化剂。反应在温和得多的条件下进行得很好,从而得到带有多种官能团的烯酮,从而为
金(III)催化开辟了一条新途径。另外,TriaAuCl 2催化剂对促进α-卤代烯酮的合成也有效。
