S Chapter 1 Study of Chiral Arylimido Molybdenum ROMP Catalysts. Molybdenum ROMP catalysts with a chiral ortho-(phenethyl)phenylimido ligand have been prepared. Mo(CHCMe2Ph)(N-2-C 6H4-CHMePh)(O-2,6-C 6H3-Ph2)2 (1la) and Mo(CHMe 2Ph)(N2-C6H4-CHMePh)[BIPHENO(Me) 2(t-Bu) 4] (11b) were isolated and shown to effect the polymerization of 2,3-dicarbomethoxynorbonadienes. Highly-trans syndiotactic poly...

A simple and convenient method of reducing monosaccharide assay is proposed. A Si(IV)-Mo(VI) solution (pH 4.9) was yellow due to the formation of the 11- and/or 12-molybdosilicate(VI) anions. By the addition of a reducing saccharide, glucosamine, the mixture turned to blue gradually, indicating that the Mo(VI) species was reduced by the saccharide to form a blue molybdosilicate anion. The molyb...

In this work a new chemically modified carbon paste electrode was constructed for accurate, simple, sensitive and selective determination of molybdenum (VI) ions. The results of modified electrode by an ion imprinted polymer were compared with those obtained with carbon paste electrode. The results showed the stripping peak currents had a dramatic increase at the modified electrode. Under the o...

Synthesis of molybdenum(vi) dioxido complexes 1-3, coordinated by one or two functionalized iminophenolate ligands HL1 or HL2, bearing a donor atom side chain or a phenyl substituent, respectively, allowed for systematic investigation of the oxygen atom transfer (OAT) reactivity of such complexes towards phosphanes. Depending on stoichiometry and employed phosphane (PMe3 or PPh3), different mol...
