 note = {Two new ene-yne substituted 2,4-pentanedionatoruthenium(III) complexes formed by the Heck-like reactions in the course of the Sonogashira reactions. The two complexes are structural isomers; one is [Ru(E-1,4-mBSima)(dpm)2] and another is [Ru(E-2,4-mBSima)(dpm)2], where E-1,4-mBSima is E-3-(1,4-bis(trimethylsilyl)-1-butene-3-ynyl)-2,4-pentanedionate, E-2,4-mBSima is E-3-(2,4-bis(trimethylsilyl)-1-butene-3-ynyl)-2,4-pentanedionate, and dpm is dipivaloylmethanate (2,2,6,6-tetramethylheptan-3,5-dionate). Both of complexes have been characterized by 1H NMR and infrared spectroscopies, mass spectrometry, and electrochemistry. [Ru(E-1,4-mBSima)(dpm)2] has also been characterized by X-ray crystallography. The ruthenium(III) is coordinated in an octahedral arrangement by the oxygen atoms of three β-diketonate ligands. The dihedral angle between the 2,4-pentanedionato chelate ring and the ene-yne plane on the E-1,4-mBSima ligand is 91°. The ene-yne group in [Ru(E-1,4-mBSima)(dpm)2] is fixed either in the solution state suggested by the 1H NMR spectrum with no symmetry., Inorganica Chimica Acta, 374(1), pp.654-659; 2011},
