Carboxylicacids are highly abundant in bioactive molecules. In this study, we describe the late-stage β-C(sp3)–H deuteration of freecarboxylicacids. On the basis of the finding that C–H activation with our catalysts is reversible, the de-deuteration process was first optimized. The resulting method uses ethylenediamine-based ligands and can be used to achieve the desired deuteration when using a

Tri-n-propylacetamide and tri-n-propylacetic acid salts are useful in the treatment of pathological variations of mood and as anticonvulsants and tranquillizers.
Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.
