Highly oxygenated fullerenes by catalytic epoxidation of C60 and single walled carbon nanotubes with methyltrioxorhenium–hydrogen peroxide
Autor: Doug Ogrin, Andrew R. Barron
Publikováno v: Journal of Molecular Catalysis A: Chemical. 244:267-270
Highly oxygenated fullerenes, C 60 O n with 3 ≤ n ≤ 9, have been prepared by the Lewis base enhanced catalytic oxidation of C 60 with ReMeO 3 /H 2 O 2 . Pyridine, pyrazole, and 2,2′-bipyridine decrease the activity of the catalyst, while 3-cyan

Publikováno v: Carbon. 47:2528-2530
An ultrafine aerosol consisting of airborne single-walled carbon nanotubes (SWCNTs) was produced by nebulizing functionalized SWCNTs in methanol. Prior to atomization, purified SWCNTs were functionalized with aryl sulfonate groups via a Birch reactio

Pd-Catalyzed Coupling of 1,2-Dibromoarenes and Anilines: Formation of N,N-Diaryl-o-phenylenediamines
Autor: Todd Wenderski, Doug Ogrin, C. Jeff Harlan, Kenneth M. Light, Simon G. Bott
Publikováno v: ChemInform. 35
1,2-Dibromoarenes were coupled with aniline derivatives to yield N,N-diaryl-o-phenylenediamines in moderate to good yield using a palladium/phosphine or palladium/carbene catalyst system. Under similar conditions, 1,2,4,5-tetrabromobenzene was couple
