资源简介:
Unprecedented Ta bis(NHC) pincer
complexes have been synthesized
and characterized by extension of the early-transition-metal amido
methodology. The reaction of 1,3-bis(3-butylimidazol-1-yl)benzene
diiodide (1) with stoichiometric and substoichiometric
amounts of (tert-butylimido)tris(dimethylamido)tantalum(V)
yielded (1,3-bis(3-butylimidazol-1-yl-2-idene)-2-phenylene)(tert-butylimido)diiodotantalum(V) (2) and (1,3-bis(3-butylimidazol-1-yl-2-idene)-2-phenylene)(tert-butylimido)(dimethylamido)iodotantalum(V) (3). Use of excess (tert-butylimido)tris(dimethylamido)tantalum(V)
to metalate 1,3-bis(3-butylimidazol-1-yl)benzene diiodide (1) yielded (1,3-bis(3-butylimidazol-1-yl-2-idene)-2-phenylene)(tert-butylimido)(dimethylamido)iodotantalum(V) (3) exclusively. Furthermore, the first early-transition-metal (group
3–5) triazole-based NHC complex, (1,3-bis(3-butyltriazol-1-yl-2-idene)-2-phenylene)(tert-butylimido)(dimethylamido)iodotantalum(V) (5), has been synthesized via amine elimination of 1,3-bis(3-butyltriazol-1-yl)benzene
diiodide (4) with (tert-butylimido)tris(dimethylamido)tantalum(V).
