A series of macrocyclic receptors has been prepared containing bipyridine groups linked to two amino acids. Variations in both the amino acid and the linking spacer have been made. The structure of the resulting macrocycles has been investigated usin

Selective palladium-catalyzed aerobic conditions of olefins and conjugated dienes with the aid of a metal macrocycle-quinone system have been developed. This involves a multistep electron transfer with three catalysts (Pd(OAc){sub 2}, hydroquinone, m

A multi-step catalytic system consisting of Pd(II)/Pd(0) - benzoquinone/hydroquinone -Fe(Pc) ox /Fe(Pc) was utilized to achieve a mild and selective aerobic oxidation of terminal olefins to methyl ketones in chloride free media.
