Abstract

Barriers to metal-arene ring rotation in [1,4-C6H4(SiMe(3))(2)]Cr(CO)(2)PPh(3) and (1,3,5-C(6)H(3)(t)Bu(2))Cr(CO)(2)PPh(3) are lowered relative to a previously reported barrier of 32 kJ mol(-1) for (1,4-C(6)H(4)(t)Bu(2))Cr(CO)(2)PPh(3). Reasons for the decreased barriers are discussed in the light of crystal structure determinations of these complexes.
