产品说明 一般描述 cis-1,4-Diacetoxy-2-butene is an ester. Ruthenium olefin metathesis catalysts having cyclic (alkyl)(amino)carbenes effectively catalyzes the cross-metathesis of cis-1,4-diacetoxy-2-butene with allylbenzene. cis-1,4-Diacetoxy-2-butene on pyrolysis affords 1-acetoxy-1,3-butadiene, a diacetate and an isomeric 1,2-diacetoxy-3-butene. Mechanism of pyrolysis has been investigated. 应用 cis-1,4-Diacetoxy-2-butene may be used in the preparation of hindered Diels-Alder adducts. It may be used for the synthesis of 1,2,3,4-tetrahydro-2-vinylquinoxalines, via Palladium-catalyzed tandem allylation of 1,2-phenylenediamines. 包装 25 mL in glass bottle 基本信息 | 线性分子式 | CH3CO2CH2CH=CHCH2O2CCH3 | | 分子量 | 172.18 | | MDL编号 | MFCD00059339 | | PubChem化学物质编号 | 24870459 | | NACRES | NA.22 |
