The condensation of 1.3-benzenedithiol with aliphatic aldehydes and ferrocenecarboxaldehyde under acid catalysis in ethanol gave 2,11 -disubstituted-1,3, I 0,12-tetrathia[3.3]metacyclophanes in poor to moderate yield. Each isolated macrocycle was found to consist of two geometric isomers, the propor
