PREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

Chelated h-cyclopentadienyl-h-ethyl complexes of molybdenum and tungsten; molecular structure of W(h-C5H4CH2-h-CH2)(CO)3

Molybdenum and tungsten complexes M(h-C5H4CH2-h-CH2)(CO)3 (M=Mo, W) containing the bidentate ethyl-functionalized cyclopentadienyl ligand C5H4CH2CH2 have been synthesized by the reaction of spiro[2.4]hepta-4,6-diene with M(CO)3L3 (M=Mo; L3=1,3,5-C6H3Me3; M=W; L=NCMe). Reaction of the more stable tungsten complex with C6H5ICl2 and HBF4 gave complexes of the type W(h-C5H4CH2CH2Cl)(CO)3Cl, W(h-C5H...

Molecular hydrogen ( H 2 ) emissions and their isotopic signatures ( H / D ) from a motor vehicle : implications on atmospheric H 2

Molecular hydrogen (H2), its isotopic signature (deuterium/hydrogen, δD), carbon monoxide (CO), and other compounds were studied in the exhaust of a passenger car engine fuelled with gasoline or methane and run under variable air-fuel ratios and operating modes. H2 and CO concentrations were largely reduced downstream of the three-way catalytic converter (TWC) compared to levels upstream, and s...
