highly efficient [(NHC)Au(I)]-based (NHC = N-heterocyclic carbene) catalytic system for the hydration of an array of alkynes that operates under acid-free conditions and at very low catalyst loadings (typically 50-100 ppm and as low as 10 ppm) was developed. Terminal and internal alkynes possessing any combination of alkyl and aryl substituents (alkyl/H, aryl/H, alkyl/alkyl, alkyl/aryl, and aryl/aryl)
一种高效的 [(NHC)Au(I)] 基(NHC = N-杂环卡宾)催化体系,用于在无酸条件和非常低的催化剂负载(通常为 50-100 ppm 和低至 10 ppm)。在本催化体系中发现具有烷基和芳基取代基(烷基/H、芳基/H、烷基/烷基、烷基/芳基和芳基/芳基)的任何组合的末端和内部
炔烃是合适的底物。
