标题:Hydroxylation Of Nitroarenes With Alkyl Hydroperoxide Anions Via Vicarious Nucleophilic Substitution Of Hydrogen
摘要:Carbo--And Heterocyclic Nitroarenes React With Anions Of Tert-Butyl And Cumyl Hydroperoxides In The Presence Of Strong Bases To Form Substituted O-And P-Nitrophenols. The Reaction Usually Proceeds In High Yields And Is Of Practical Value As A Method Of Synthesis And Manufacturing Of Nitrophenols. Orientation Of The Hydroxylation Can Be Controlled To A Substantial Extent By Selection Of The Proper Conditions. Basic Mechanistic Features Of This Process Were Clarified.

摘要:The present invention relates to a method for covalently attaching nucleosides and/or nucleotides on surfaces having reactive functional groups, where in a first step, the reactive functional groups are made to react with suitable derivatized nucleosides and/or nucleotides, and in a second step, they are converted with a protecting group reagent, so that a reaction product of the consecutive reaction interacts with electromagnetic radiation such that it can be quantitatively determined. The invention also relates to a method for determining the repetitive coupling yields in the synthesis of nucleotides where the free 3′ or 5′ hydroxy group of a selected nucleoside and/or nucleotide is converted with a compound of formula (I) n n nwhere L is a common suitable leaving group, the motif O—PX represents a phosphor amidite, a H-phosphonate a phosphonic acid ester, a phosphotriester, Yâ•?O or S, N is a nucleoside or a nucleotide derivative which subsequently reacts further with a protecting group reagent and the elimination of the leaving group (L), which is subsequently further eliminated. The quantity of the leaving group (L) eliminated in step b) is quantitatively determined in the form of its anion (L − ) by means of otical spectroscopy.

标题 :Process for the preparation of high activity hydrocarbon synthesis catalysts; and catalyst compositions
发明人：CULROSS CLAUDE C
权利人:EXXON RESEARCH ENGINEERING CO
摘要:A process for the preparation of a catalyst which is highly active for the synthesis of hydrocarbons from mixtures of hydrogen and carbon monoxide. A silica or silica-containing support is treated with a solution containing both an Iron Group metal, or metals, and nitrous acid, nitric acid, or a nitro-containing organo, or nitro-containing hydrocarbyl compound, or compounds, sufficient to hydroxylate the surface thereof and increase the number of hydroxyl groups on the surface of the support such that the metal component will be highly dispersed, this increasing the activity of the catalyst in a hydrocarbon synthesis reaction as contrasted with that of a catalyst of similar composition, similarly prepared except that the support component of the catalyst was not contacted and simultaneously treated with both the Iron Group metal and the acid.

摘要:THIS INVENTION DEALS WITH A NOVEL, RELATIVELY SIMPLE PROCESS OF PREPARING POLYBENZOTHIAZOLINES, ((-NH-CH(-)-S-)>AR<(-NH-CH(-Z(-))-S-))N BY REACTING DIALDEHYDES, Z-(CH=O)2, AND (HS)2-AR(-NH2)2 IN A SOLVENT IN AN INERT ATMOSPHERE AND THEREAFTER OXIDIZING THE POLYBENZOTHIAZOLINES TO POLYBENZOTHIAZOLES, ((-N=C(-)-S-)>AR<(-N=C(-Z(-))-S-))N WHEREIN AR REPRESENTS A TETRAVALENT AROMATIC MOIETY IN WHICH THE NITROGEN AND SULFUR ATOMS IN EACH PAIR ARE DISPOSED ORTHO TO EACH OTHER AND Z REPRESENTS A DIVALENT HYDROCARBON MOIETY AS THE RESIDUE OF THE DIALDEHYDE, Z(CHO)2. NEW TYPES, AS WELL AS THE KNOW TYPES OF POLYBENZOTHIAZOLES HAVE BEEN PREPARED BY THIS PROCESS.
