N2 - gamma,gamma'-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. (C) 2001 Elsevier Science Ltd.
