产品说明 一般描述 Diethyl chloromalonate (Diethyl α-chloromalonate) is a 2-halo-1,3-dicarbonyl compound. It participates in K2CO3-catalyzed domino reactions (Michael alkylation, Mannich alkylation, and aldol alkylation) of salicylic aldehyde derivatives to afford functionalized 2,3-dihydrobenzofurans. It reacts with Cs2CO3 in the presence of elemental S8 or Sen to afford the corresponding diethyl thioxo- or selenoxomalonates, which can be trapped in situ with various 1,3-dienes. 包装 5, 25 mL in glass bottle 基本信息 | 线性分子式 | ClCH(CO2C2H5)2 | | 分子量 | 194.61 | | EC 号 | 237-913-0 | | MDL编号 | MFCD00009140 | | PubChem化学物质编号 | 24867397 | | NACRES | NA.22 |
