Catalyst isomerization between E isomer and Z isomer of the 1,2,3,3,3 penta- fluoro propene which uses the aluminum catalystWhen the starting material which includes 1,2,3,3,3 penta- fluoro propene, kurorohutsu aruminiumu (AlCl ) is made to contact with the catalyst, Z/E ratio of 1...
(Z)-异构体 1. An HPLC-electrochemical detection method was established for the determination of entacapone and its related substances, (Z)-isomer of entacapone and 3,4-dihydroxy-5-nitrobenzaldehyde. 建立了高效液相色谱-电化学检测法测定恩他卡朋及其有关物质[(Z)-异构体和3,4-二羟基-5-硝基苯...
We have investigated the Z/E isomerism of the hydrazide link (CO-NH-N) and amidoxy link (CO-NH-O). The study was first focused on small molecular models using NMR and X-ray diffraction. It allowed determination of simple NMR criterions to differentiate easily the Z and E forms, which...
