Rw. Matthews et al., METAL-ION-DIRECTED SYNTHESIS OF SULFUR-BASED MACROCYCLIC HELICATES, Journal of the Chemical Society. Dalton transactions, (17), 1997, pp. 2861-2863
Schiff-base condensation of pyridine-2,6-dicarbaldehyde and minophenyl
)sulfanyl]methyl}benzyl)sulfanyl]aniline led to different helical macr
ocyclic products depending on the template metal ion; a mono-helical [
1 + 1] macrocyclic complex was generated in the presence of Ag-I and a
double-helical [2 + 2] macrocyclic complex was generated in the prese
nce of Cd-II.
