Barriers to metal-arene ring rotation in [1,4-C6H4(SiMe3)2]Cr(CO)2PPh3 and (1,3,5-C6H3tBu2)Cr(CO)2PPh3 are lowered relative to a previously reported barrier of 32 kJ mol-1 for (1,4-C6H4tBu2)Cr(CO)2PPh3. Reasons for the decreased barriers are discussed in the light of crystal structure determinations of these complexes.
