Abstract
The influence of both the central metal atom and ligands on the product distribution and the stereoselectivity of reduction and isomerization of oxiranes and α-diazoketones by early transition metallocenes is investigated. Generally oxiranes are reduced to the corresponding alkenes, however isomerization occurs with terpenes containing a terminal oxirane function to give aldehydes or allylic alcohols. The majority of the metallocenes reduce α-diazoketones to their parent ketones.Keywords
