New heterodinuclear ruthenium(II) bipyridyl-transition metal dithiocarbamate macrocycles have been prepared in good yields via metal directed self-assembly and shown to recognise anions. 1 H NMR anion titration studies reveal the nature of the bipyridyl amide metal dithiocarbamate spacer unit in the respective dinuclear metal macrocycle influences significantly the strength of chloride and...
The condensation of 1,3-benzenedithiol with aliphatic aldehydes and ferrocenecarboxaldehyde under acid catalysis in ethanol gave 2,11-disubstituted-1,3,10,12-tetrathia[3.3]metacyclophanes in poor to moderate yield. Each isolated macrocycle was found to consist of two geometric isomers, the proportions of which varied with each aldehyde used. Variable temperature NMR studies confirmed the extreme...
