Investigations of ruthenium halfsandwich complexes have mostly focused on Cp and Cp* based derivatives due to the availability of easily accessible starting materials. However, it is interesting to have complexes with substituted cyclopentadienyl ligands i ...

RhCl3 is shown to mediate unusual coupling reactions of tert-butyl acetylene. When RhCl3(H2O)n was heated with four equivalents of tert-butyl acetylene in methanol, the dinuclear complex [{Rh(μ-Cl)(CH2tBu)(tBuC=CHCOCH2tBu)}2] (2) was isolated. A larger exc ...

Cyclopentadienyl-ruthenium half-sandwich complexes with 2-bound alkyne ligands have been suggested as catalytic intermediates in the early stages of Ru-catalyzed reactions with alkynes. We show that electronically unsaturated complexes of the formula [RuCl ...

The dimeric ruthenium complex Cp^RuCl2 is easily accessible in a one-pot reaction from RuCl3(solv)(n) and tert-butylacetylene. It features sterically very demanding "Cp-roof" ligands (Cp^ = eta(5)-1-methoxy-2,4-tert-butyl-3-neopentylcyclopentadienyl), ...

The water-sol. complexes [(Cp'OR)RuCl(PTA)2] (Cp'OR = h5-1-alkoxy-2,4-di-tert-butyl-3-neopentylcyclopentadienyl; R = Me, Et; PTA = 1,3,5-triaza-7-phosphaadamantane) are considerably more cytotoxic (.apprx.2 orders of magnitude) than the cyclopentadienyl an ...
