A novel complex Cu(PPh3)2(acac) 1 (PPh3 = triphenylphosphine, acac = acetylacetone) was obtained by a solution reaction and structurally characterized by X-ray
Polybutene-1 was synthesized stereoselectively with the precursorη5-(pentamethyl-cyclopentadienyl) tribenzyloxide titanium (Cp*Ti(OBz)3) and methylaluminoxane
