Expedient Method for the Transmetalation of Zn(II)-Centered Salphen Complexes

Various mono- and bis-ZnII complexes derived from salphen ligands
have been conveniently transmetalated with a number of transition
metal (TM) acetates (M = Ni, Pd, Mn) in THF to afford their
respective TM−salphen counterparts in excellent isolated yields
(80−100%). This new transmetalation procedure allows in situ
switching between supramolecular and catalytic functions of the
metallosalphen complex.

以水杨醛缩邻苯二胺（salphen）配体衍生得到的多种单核及双核二价锌配合物，可在四氢呋喃（THF）中与多种过渡金属（transition metal, TM）乙酸盐（M = Ni、Pd、Mn）进行便捷的转金属化反应，以80%~100%的优异分离产率得到对应的过渡金属salphen配合物。该新型转金属化方法可实现金属salphen配合物的超分子功能与催化功能之间的原位切换。
