The evaluation of the kinetics of dediazoniation of benzenediazonium tetrafluoroborate and p-chlorobenzenediazonium tetrafluoroborate in 1,2-dichloroethane at 50Β°C in the presence of 18-crown-6,
Complexes between the heavier lanthanoid nitrates Ln(NO~3~)~3~ and 15βcrownβ5 (**1**) and 18βcrownβ6 (**2**) ethers were isolated and characterized. Both 1:1 and 4:3 complexes are formed with each Ln(III) ion, except in the case of Gd and **2**. The thermal transformation of the 1:1 complexes into t
