Abstract

The role of architecture and nanoenvironment in the catalytic properties of dendritic polymers containing 4-(dialkylamino) pyridines was investigated in the context of acylation reactions employing sterically demanding tertiary alcohols as substrates. Fréchet-type benzyl ether and aliphatic ester dendrimers were prepared in a convergent manner from a common trivalent core containing three DMAP groups while a linear polymer was ...
