Abstract:

[M(CpBz)(CO)3CH3] (M=Mo, 2a, W, 2b; CpBz=C5(CH2Ph)5) have been prepared and reacted with PCl5 and PhI · Cl2. Depending on the metal and on the chlorinating reagent used [Mo(CpBz) ($η$2-COCH3)Cl3], 3, [W(CpBz)Cl4], 4, [Mo(CpBz)(CO)3Cl], 5 and [Mo(CpBz)Cl4], 6 have been obtained. The molecular structures of all compounds are reported and two conformations have been characterised for the benzyl substituents. In complexes 2a, 2b and 5 one phenyl ring bends towards the metals while in 3 and 4 the five phenyls point opposite to the metals. © 2004 Elsevier B.V. All rights reserved.
