专利号:US-8841473-B2 优先权日:2009-09-01 标题 :Synthesis of fluorosilicones and their derivatives 发明人:MARCINIEC BOGDAN; MACIEJEWSKI HIERONIM; DABEK IZABELA; KARASIEWICZ JOANNA 权利人:MARCINIEC BOGDAN; MACIEJEWSKI HIERONIM; DABEK IZABELA; KARASIEWICZ JOANNA; UNIV ADAM MICKIEWICZ 摘要:The subject of invention is the method of synthesis of fluorosilicone co-polymers of arbitrary topology and general formula 1 in which among others if A stands for CH—O(CH 2 ) m (CF 2 ) n CF 2 H group, then the method is based on hydrosilylation reaction of appropriate fluoroalkyl-allyl ether with polyhydrosiloxanes containing at least one Si—H group, catalyzed by siloxide rhodium complex. If A stands for in which Z stands for divalent group either then the method is based on the reaction of nucleophilic opening of oxirane ring in appropriate epoxyfunctional co-polysiloxanes, in acidic environment.

Also provided herein is amorphous obicetrapib hemicalcium. New intermediates for use in the synthesis of obicetrapib, and salts thereof are also provided, including obicetrapib HCl and a mesylate salt for the use in the synthesis of obicetrapib and amorphous obicetrapib hemicalcium.
专利号:US-6150499-A 优先权日:1998-01-06 标 题:Process for preparation of TFPX-dichloride 发明人:DOLBIER JR WILLIAM R; DUAN JIANXIN 权利人:SPECIALTY COATING SYSTEMS INC 摘要:A method for the synthesis of TFPX-dichloride is disclosed. The method involves reacting hexachloro-p-xylene with anhydrous HF in an inert organic solvent. The reaction is advantageous in that it produces relatively high yields of TFPX-dichloride, provides little waste, and is carried out as a simple, one-step process.
专利号:WO-2024019698-A1 优先权日:2022-07-18 标题 :Photocatalytic synthesis of alpha, beta unsaturated carbonyl compounds and their intermediates 发明人:SUGURI TAKUYA; MARUYAMA YOUICHIROU; LIM CHERN-HOOI; QIAN GANG; LIU YUE; COPE ELANA 权利人:JSR CORP; NEW IRIDIUM INC 摘要:Described herein is a process of producing α,β unsaturated acids and amides and their intermediates via a photocatalytic reaction in the presence of a photocatalyst, oxygen, and optionally a solvent. The photocatalyst contains a tungstic acid or a salt of a tungstic acid. The process is simple, clean, and energy efficient, and provides good conversion, good selectivity, good turnover, and easy purification of end products.
