摘要：
Addition of a stoichiometric amount of KR (R = CH2C6H4-o-NMe2, C6H4-o-CH2NMe2, CH2C6H5) to a solution of Sm(Tp(Me2))(2)Cl in toluene or THF led to the immediate formation of the insoluble, purple Sm(Tp(Me2))(2) compound. However, when these reactions are carried out in the presence of protic substrates such as HOPh, HCp, HCCPh, HOC6H2-2,4,6-'Bu-3, HNPh2 and 3,5-Me(2)pzH. the corresponding Sm(Tp(Me2))(2)(Y) compounds (Y = OPh (1), CCPh (2). Cp (3). OC6H2-2,4,6-'Bu-3 (4), NPh2 (5), 3,5-Me(2)pz (6)) readily form and in good yields, The structures of 4-6 have been established by X-ray crystallography. (C) 2001 Elsevier Science BN.
