A new ditopic pyrimidine-hydrazone ligand, 6-hydroxymethylacryloyl-2-pyridinecarboxaldehyde, 2,2'-[2,2'-(2-methyl-4,6-pyrimidinediyl)bis(1-methylhydrazone)] (L2), was synthesized with terminal acryloyl functional groups to allow incorporation into copolymer gel actuators. NMR spectroscopy was used to show that L2 adopted a horseshoe shape with transoid-transoid pym-hyz-py linkages. Metal complexation

A new series of phenylpyrido[4,3-d]pyrimidin-2-amin derivatives have been synthesised from the reaction of (E)-3,5-bis(benzylidene)-4-piperidones and guanidine carbonate in the presence of (Fe2O3)-MCM-41-nPrNH2 as a magnetically recoverable nanocatalyst under solvent free conditions. This catalyst was highly recyclable (up to 5 times)
