The photolysis of NH3 in the presence of substituted acetylenes: A possible source of oligomers and HCN on Jupiter

Autor: Jean Claude Guillemin, Richard R. Jacobson, James P. Ferris

Publikováno v: Icarus. 95:54-59

Photolysis of NH3 in the presence of propyne yields dimethylketazine (4) as the main product along with dimethylketimine, isopropylamine, and propioazine (7). Dimethylketazine and isopropylamine are the principal reaction products when the photolysis

Publikováno v: Tetrahedron Letters. 32:7499-7502

Photorearrangement of N-carbomethoxynorcodeinone (1) in the presence of oxalic acid gives the chiral biaryl 3, which is converted to the protostephanine analogue 4b in 70% overall yield.

Reactivity patterns and comparisons in three classes of synthetic copper-dioxygen {Cu2-O2} complexes: implication for structure and biological relevance

Autor: Zoltan Tyeklar, Partha P. Paul, Kenneth D. Karlin, Richard R. Jacobson

Publikováno v: Journal of the American Chemical Society. 113:5322-5332

We have recently characterized three classes of peroxodicopper (II) complexes, which are formed reversibly from the reaction of Cu (I) precursors (1-3) with O 2 at −80 o C in solution. Here, we detail and compare the reactivities of [Cu 2 (XYL-O-)(
