Lewis acid promoted terminal-to-bridge carbonyl shift in [(π-C5H5)Ru(CO)2]2

Abstract

Solution i.r. spectra demonstrate that in the presence of AIR₃ the non-bridged form of [(π-C₅H₅)Ru-(CO)₂]₂ is converted into CO-bridged adducts containing AIR₃ co-ordinated to the oxygen(s) of the bridging carbonyls.
