Abstract

Addition of a stoichiometric amount of KR (R = CH2C6H4-o-NMe2, C6H4-o-CH2NM e2, 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. Howe ver, when these reactions are carried out in the presence of protic substra tes such as HOPh, HCp, HCCPh, HOC6H2-2,4,6-'Bu-3, HNPh2 and 3,5-Me(2)pzH. t he 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 goo d yields, The structures of 4-6 have been established by X-ray crystallogra phy. (C) 2001 Elsevier Science BN.
