标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

标题:Chemical amplification for the synthesis of patterned arrays

摘要:Radiation-activated catalysts (RACs), autocatalytic reactions, and protective groups are employed to achieve a highly sensitive, high resolution, radiation directed combinatorial synthesis of pattern arrays of diverse polymers. When irradiated, RACs produce catalysts that can react with enhancers, such as those involved in autocatalytic reactions. The autocatalytic reactions produce at least one product that removes protecting groups from synthesis intermediates. This invention has a wide variety of applications and is particularly useful for the solid phase combinatorial synthesis of polymers.

标题 :Method for preparing a bimetallic ruthenium/tin catalyst and a process for the synthesis of aldehydes
发明人：JACQUOT ROLAND
权利人:RHODIA CHIMIE SA
摘要:The present invention relates to a new process for the preparation of a bimetallic ruthenium/tin catalyst. The process for the preparation of a bimetallic ruthenium/tin catalyst according to the invention is characterised by the fact that it consists in carrying out the reduction of a ruthenium complex having an electrovalency of -4 and a coordination number of 6, the ligands being either a halogen atom or an anion or a tin halide. The catalyst is further employed for the preparation of aldehydes by reduction, in the vapor phase, of carboxylic acids, esters and anhydrides.

权利人:MOLECULAR PROBES INC
摘要:Facile syntheses for fluorinated resorcinol and aminophenol derivatives are provided that yield isomer-free products in good yield. These novel methods use generally available precursors and standard laboratory reagents and equipment to reproducibly produce these synthetically useful reagents in relatively large quantities. The resulting fluorinated resorcinols and aniinophenols possess utility in the preparation of fluorinated fluorescein and rhodol dyes.

标题 :One step synthesis of methyl t-butyl ether from t-butanol using haloacid-modified clay catalysts
发明人：KNIFTON JOHN F
权利人:TEXACO CHEMICAL
摘要:A method is disclosed wherein t-butanol is reacted with methanol in a reaction zone in one step to provide methyl tert-butyl ether and the improvement of accomplishing the reaction which comprises: n a. Using a catalyst comprising a montmorillonite clay treated with a haloacid; n b. continuously contacting said t-butanol and methanol in a molar amount of about 0.1 to 10 moles of methanol per mole of t-butanol with said catalyst at a temperature of about 20° C. to about 250° C. and a pressure of about atmospheric to about 1000 psig to obtain the methyl tert-butyl ether product.
