Mannich aminomethylation reaction of aromatic thiols has been used to produce diaza-18-crown-6ligandscontainingthiol-derivedsidearms. Thiophenols were attached to the azacrown through N-CH2-S linkages even in the presence of hydroxy or acetamido groups. Heteroaromatic thiols containing N=C-SH (or NH-C=S) structural fragments were attached to diaza-18-crown-6 by N-CH2-N linkages with the thiol becoming
