Abstract

γ,γ′-Ester functionalisation of the macrocycle 5,7,12,14-tetramethyldibenzo[b,i ]-1,4,8,11-tetraazacyclotetradecinenickel-(II) (Ni(TMTAA)), using two alternative methods, either based on oxalyl chloride or 'triphosgene', has been effective in the synthesis of novel cyclic crown ether-type molecules containing a rigid, saddle shaped nickel(II) macrocycle and an oligoethyl ether chain. Mono-ester derivatisation using triphosgene allows access to compounds with two Ni(TMTAA) units bridged by oligoethyl ethers of various chain length.
