[(Cp-R)M(CO)3] (M= Re or 99mTc) Conjugates for Theranostic Receptor Targeting
Cyclopentadienyl complexes of 99mTc became accessible via a retro Diels-Alder synthetic approach of dimerized cyclopentadiene derivatives. So far, this approach was limited to derivatives comprising a carboxylic acid group, directly conjugated ...
