摘要:A method for the solid-phase synthesis of a target oligonucleotide OT is disclosed, wherein said method comprises a step of incubating a nucleoside or oligonucleotide, which is covalently linked to a solid support and comprises a backbone hydroxyl moiety protected by a di(p-methoxyphenyl)phenylmethyl (DMT) protecting group, with a deprotection mixture, thereby cleaving said protecting group from said nucleoside or oligonucleotide, wherein said deprotection mixture is a liquid composition comprising a solvent, a protic acid having a pKa equal to or smaller than 4, and at least one alcohol of Formula (D), wherein in RD-1 R,D-2 R,D-3 RD-4 and RD-5 are indepently of each other selected from the group consisting of H, OH, a e1-e6-alkyl group, O(C1-C6-aIkyl), C(O)(Ci-C6-alkyl), C(O)O(Ci-C6-alkyl), F, Cl, Br, I, and CN. Such a method does not only suppress depurination, but also results in an acceptable product yield.

标题 :Nanocatalyst anchored onto acid functionalized solid support and methods of making and using same

权利人:HEADWATERS NANOKINETIX INC
摘要:Supported catalysts include a solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. Active catalyst particles are supported on the functionalized support material. The acid functionalized support material is made by reacting a solid support with an inorganic acid containing agent such as sulfuric acid or para-toluene sulfonic acid. An organic anchoring agent is used to form and anchor catalyst nanoparticles to the acid functionalized support material. The supported catalyst can be sized and shaped for use in any type of reactor, including a fixed bed or fluidized bed reactor. The methods of the present invention also include a process for the direct synthesis of hydrogen peroxide using the supported catalyst.

摘要:Supported catalysts include an inorganic solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. The functionalization of the support material is optimized by (i) limiting the amount of water present during the functionalization reaction, (ii) using a concentrated mineral acid or derivative thereof, and/or (iii) increasing the reaction temperature and/or reaction pressure. The acid-functionalized support material serves as a support for a metal nanoparticle catalyst. The nanocatalyst particles are preferably bonded to the support material through an organic molecule, oligomer, or polymer having functional groups that can bind to both the nanocatalyst particles and to the support material. The supported catalysts can advantageously be used for the direct synthesis of hydrogen peroxide from hydrogen and oxygen feed streams.
