suspected. To evaluate if the O atom in the product originates from the hydroxide in
125, the reaction was repeated with an
18 O-labeled analog unequivocally proving the
relevance of the bimetallic species to oxidation catalysis. It was also demonstrated
that the very distinctive donor arrays offered by this design allow synthesis and full
characterization of a series of copper-cooper, copper-palladium, and copperplatinum bimetallic complexes (127–129) for further structure-reactivity studies
(Scheme 50) [123].
4 Conclusions
As evident by the consistently high number of publications on the chemistry of
pincer complexes in the past 35 years, they remain in the domain of very intense
academic activity owing to their high chemical and thermal stability as well as their
