Selective mono-N-alkylation of triethylenetetraamine. A new versatile route to polylinear aza-ligands
A new route to triethylenetetraamine selective mono-N-alkylation on secondary nitrogen atom using simultaneously bisaminal and diamide protections is presented and applied to the synthesis of poly-linear aza-ligands.

Synthesis of novel cyclodextrin derivatives by aromatic spacer insertion and their inclusion ability
Novel cyclic host molecules were synthesized by the insertion of three types of aromatic spacers into the skeleton of permethylated α-cyclodextrin. These host molecules formed a 1:1 complex with sodium 3- and 4-nitrobenzenesulfonates (3- and 4-NBS), and s
Facile preparation of benzylic iodides under solvent-free conditions using microwave irradiation
Benzylic alcohols are rapidly converted to the corresponding benzylic iodides using combination of p-toluenesulfonic acid (PTSA) and potassium iodide under solvent-free microwave irradiation conditions.
