Abstract
The synthesis and characterisation of [Ru(H)(eta(5)-3-phenylindenyl)-( Bu-i-Phoban)(2)] 4 is reported (Bu-i-Phoban = 9-isobutyl-9-phosphabicyclo-[3.3.1]-nonane). 4 is obtained via alcoholysis of metathesis pre-catalyst M-11, in a process that was previously thought to be limited to analogous complex [RuCl2(PPh3)(2)(3-phenylindenylidene)] (M-10).
