专利号:US-5714649-A 优先权日:1993-07-20 标题 :1-Halo-cis-3-tetradecenes and processes for the preparation of cis-Olefin compounds by using same 发明人:FUKUMOTO TAKEHIKO; IWAI DAISUKE; OKANO SHIGEO; SUZUKI HIROSHI; OSHIMA MITSUYOSHI 权利人:SHINETSU CHEMICAL CO 摘要:Disclosed are compounds suitable for use as raw materials which enable cis-olefin compounds useful as physiologically active substances such as the sex pheromones of various insects, or as intermediates for the synthesis thereof to be prepared on an industrial scale at a reasonable cost, and processes for the preparation of cis-olefin compounds by using the same. For this purpose, novel compounds (i.e., 1-halo-cis-3-tetradecenes) of the general formula (I) CH3(CH2)9CH=CH(CH2)2X(I)wherein X is a halogen atom, are used as raw materials for the preparation of cis-olefin compounds.

Monomeric reagents having the structural formula (I) ##STR1## wherein R 1 , R 2 , R 3 , R 4 and R 5 are as defined herein, are used to create polynucleotides having nonnucleotidic moieties -A-Z-(R 9 ) n at the 1 position of selected deoxyribose units. The polynucleotides so provided are useful in a variety of hybridization assay formats.
专利号:US-5936132-A 优先权日:1994-03-11 标题 :Alkene intermediates and synthesis thereof 发明人:MATSUMOTO MASAKATSU 摘要:A chemiluminescent 1,2-dioxetane derivative having a formula (I): ##STR1## wherein R 1 and R 4 each represent, individually, hydrogen, an alkyl group, an alkoxyl group, a hydroxyl group, or --OS;(R 9 R 10 R 11 ) in which R 9 , R 10 and R 11 each represent an alkyl group; R 2 , R 3 , R 5 and R 6 each represent, individually, hydrogen or an alkyl group, provided that R 2 , R 3 , R 5 and R 6 each cannot be hydrogen at the same time, and that R 2 and R 3 , and R 5 and R 6 , each taken together, can form a cycloalkyl group; R 7 represents an alkyl group; R 8 represents hydrogen, an alkoxyl group, a phosphate salt group, or --OSi(R 9 R 10 R 11 ); intermediates for synthesizing the above 1,2-dioxetane derivative; and methods of producing the intermediates are provided.
专利号:US-2025188235-A1 优先权日:2022-03-14 标题 :Anion exchange membrane and method of making 发明人:YANDRASITS MICHAEL A; LINDSAY MARIA C 权利人:3M INNOVATIVE PROPERTIES COMPANY 摘要:A method for making an anion exchange membrane is provided. A neutral precursor polymer that contains pendant groups that contain a leaving group is converted to a cationic polymer prior to forming the membrane. The cationic polymer contains pendant groups with a quaternary amino group. This method eliminates the need for multiple wet process steps on the membrane after its formation. Further, this method can improve the ease of solvent capture and recycling compared to previous synthesis methods because these steps occur prior to membrane formation.
