金催化剂— 21世纪的′淘金热′
三氟甲磺酸银是一种反应性三氟甲烷磺酸试剂，可作为可溶性银离子来源，用于亲电络合阳离子合成，促进傅-克烷基化、亲核烯烃环化和酯化反应。
它还可用于：
  • 从仲磷酸盐和硫代磷酸盐获取烯烃。
  • 用作在温和条件下醚化醇和伯烷基卤化物的试剂。
  • 从氯铑配合物中制备用于乙炔加氢磷酸化的阳离子铑催化剂。
  • 用作通过醛的硅氢加成，制备甲硅烷基醚的催化剂。

A novel rhodium-catalyzed hydrophosphination of alkynes using a silylphosphine as a phosphino group source is described. A variety of alkynes, both terminal and internal ones with aryl, alkyl, and carboxyl groups, gave the corresponding alkenylphosphines in a highly regioselective and

A novel gold-catalyzed method for the regioselective synthesis of highly substituted pyrroles directly from oximes and alkynes was developed via independent optimization of two key steps of the process. Importantly, a cationic gold(I) species was shown to activate multiple steps
