摘要：

The cationic tris-MeCN adducts of Tp(R)M fragments, [Tp(R)M(NCMe)(3)]OTf [Tp(R)=hydrotrispyrazolylborato, R=3-Ph-5-Me (1), 3,5-iPr(2) (1'); M=Ni, Co], were prepared by chloride abstraction from the corresponding chloro complexes, Tp(R)M-Cl (2), with AgOTf in acetonitrile. The MeCN ligands in 1 and 1' are labile enough to be readily converted to a variety of adducts, [Tp(R)M(L)(n)]OTf, via treatment with N- and P-donors [NC(CH2)(2)CN, p-NCC6H4CN, pyridine, o-bipy, p-bipy, Ph2P(CH2)(m)PPh2 (m=2,3)].
