Syntheses and molecular structures of some polyfluoroaryldiynyl–ruthenium complexes
摘要:
Lithiated Ru(C CC CH)(dppe)Cp* reacts with polyfluoroaromatic compounds C6F5X (X = F, OMe, CN, NO2) and C10F8 to give novel polyfluoroaryldiynyls end-capped with the Ru(dppe)Cp* group. Addition of tcne to Ru(C CC CC6F5)(dppe)Cp* afforded the butadienynyl Ru{C CC[ C(CN)(2)]C(C6F5) C (CN)(2)}(dppe)Cp*, while protonation with HBF4 center dot OEt2 resulted in cycloaddition to give [1,3-{Cp*(dppe) RuC C}(2){mu-C4H(C6F5)(2)}]BF4. XRD molecular structures of complexes with X = F, CN, OMe and the C10F7 derivative are reported. (C) 2010 Elsevier B. V. All rights reserved.
