diazoacetates and N,N-disubstituted diazoacetamides and the subsequent formation of lactones and lactams, respectively. The complexes containing the ligands TpBr3 or TpMs have provided activities and selectivities for these transformations comparable with or, in some cases, better than the well-known rhodium catalyst Rh2(OAc)4.
已经测试了一系列的Tp x Cu配合物(Tp x =氢三
吡唑基
硼酸酯配体)作为催化剂,用于分解几种
重氮乙酸酯和N,N-二取代的重氮乙酰胺,随后分别形成内酯和内酰胺。包含
配体Tp Br3或Tp Ms的配合物为这些转化提供了与众所周知的
铑催化剂Rh 2(OAc)4相当或在某些情况下更好的活性和选择性。
