Thermosetting resin compositions are provided that are useful for mounting onto a circuit board semiconductor devices, such as chip size or chip scale packages (“CSPs”), ball grid arrays (“BGAs”), land grid arrays (“LGAs”) and the like (collectively, “subcomponents”), or semiconductor chips. Reaction products of the compositions are controllably reworkable when subjected to appropriate conditions.

The synthesis of piano-stool type complexes [(Cp-R)99mTc(CO)3] from water and, if possible, directly from [99mTcO4]- is a persisting challenge. Such complexes are very convenient for labelingbiomolecules since they are small in size and “innocent” with respect to noncovalent interactions in biological systems. We found that [(Cp-R)99mTc(CO)3] can be prepared directly from the dimerized Diels−Alder
