Abstract

The thermal and photochemical behaviour of the organotetraruthenium clusters [Ru4(CO)12(PhC2R)] (R = Me or H) and [Ru4(CO)11(PhC2Me)2] is described. Interestingly the reactions of these complexes with phosphorus donor ligands are highly regioselective, as determined by variable-temperature n.m.r. studies. The dynamic behaviour of [Ru4(CO)10{P(OMe)3}(PhC2Me) 2] shows for the first time the occurrence of a 'merry-go-round' CO exchange process around the quasi-planar Ru4 framework.
