The solvent is key: A general protocol is described for the hydrostannylation of propargyl alcoholderivatives at roomtemperature using Et3B/O2 as the promoter (see scheme). Rate and mechanistic studies point to a different autoxidation product of Et3B in THF than is observed in benzene, the typical solvent.
溶剂是关键:描述了在室温下使用Et 3 B / O 2作为促进剂进行炔丙醇衍生物加氢苯乙烯化的通用方案(请参见方案)。速率和机理研究表明,Et 3 B在THF中的自氧化产物与在典型溶剂苯中观察到的不同。
