Ring tilting and the barriers to rotation of arene rings π-bonded to transition metals
Abstract
Restricted rotation of the arene ring in complexes of the type (arene)M(CO)3-x(SiCl3)x(M = Re, x= 1; M = Ru, Os, x= 2) appears to occur when the ring is prevented from tilting by the presence of two bulky groups on both the arene ring and the transition metal.
