摘要:

AbstractThe terdentate aryldiamine ligand in the aryltantalum(V) alkylidene complex [TaCl2{C6H3(CH2NMe2)2‐2,6}(CHBut)] (1) controls alkylidene reactivity in a range of metal‐mediated Wittig reactions. An X‐ray diffraction study of (1) shows that the hexacoordinate tantalum centre has a very irregular ligand array in which the aryldiamine ligand adopts a newfacialN,C,N coordination
