COORDINATION CHEMISTRY OF SILOLES:A NEW ASPECT OF THE STEREOCHEMICAL BEHAVIOUR OF (η4-exo- AND -endo-1-CHLORO-2,5-DIPHENYLSILACYCLOPENTADIENE)TRICARBINYLIRON COMPLEXES

It has been shown that (η⁴-1-chloro-2,5-diphenylsilacyclopentadiene)tricarbonyliron complexes undergo nucleophilic displacements at silicon with complete retention of configuration at both exo and endo positions.The substitution is faster at the exo than at the endo position.The observations are discussed in terms of electronic factors.
