Multifaceted chemical behaviour of metallocene (M = Fe, Os) quinone methides. Their contribution to biology

Organometallic quinone methides (OM-QMs) have unique chemical and biological properties compared to their purely organic counterparts, but their originality has not previously been delineated in review form. These phenomena are particularly evident when they are incorporated into a judiciously chosen substrate, in this specific case the ferrocifens, bioorganometallic modifications of hydroxytamoxifen, the antiestrogen of reference. The newly …
