A short route to cyclopentadienyltricarbonylrhenium substituted derivatives
Le Bideau,Hénique,Pigeon,Joerger,Top,Jaouen
, p. 140 - 144 (2007/10/03)
CpRe(CO)3 substituted derivatives were obtained in good yields (44-96%) from fulvenes and Re2(CO)10 in boiling mesitylene. This new methodology was applied to the synthesis of CpRe(CO)3 substituted steroids with success.
