Rh(I) complexes of S-triazines were found very efficient towards the catalytic hydrogenation of alkenes, alkynes at normal pressure and at room temperature. Reduction of aromatic nitrocompounds, benzaldehyde and benzil were observed in appreciable amount only at high pressure and at high temperature. No diminished catalytic activity was observed even after 6-8 repeated catalytic runs. Profound ...

Some new isomeric structures of pyrimido[2,1-c][1,2,4]triazines 4-8 and 10-14 have been synthesized via the ring closure reactions of 2-hydrazinyl-1-methylpyrimidine 3 and/or 2-hydrazinopyrimidine 9 with acyclic and cyclic oxygen compounds under various conditions. Structures of the targets have been established from their elemental analyses and spectral data (UV, IR, 1H/13C NMR and mass spectr...

Immunochemical assays for small molecules such as pesticides are rapidly gaining acceptance among analytical chemists. These techniques are rapid, sensitive, cost effective and can easily cope with large sample loads. This review lists the advantages and disadvantages of the technique and describes the steps in assay development using examples from this laboratory, particularly the thiocarbamat...
