A commercially available catalyst system comprising Pd(OAc)2 or Pd2(dba)3 and the proazaphosphatrane ancillary ligand P(i-BuNCH2CH2)3N (1) for the amination of aryl halides substituted with a phenol, alcohol, acetanilide, amide or ketone group containing an enolizable hydrogen is described. The reaction is performed in the presence of LiN(SiMe3)2 as the base. Other bases tested were either less effective
包含Pd(OAc)2或Pd 2(dba)3和原氮杂磷杂环戊烷辅助配体P(i- BuNCH 2 CH 2)3 N(1)的市售催化剂体系,用于胺化被苯酚,醇,描述了含有可烯醇化氢的乙酰苯胺,酰胺或酮基。反应在LiN(SiMe 3)2作为碱的存在下进行。所测试的其他基础不是很有效,就是完全没有功能。
