Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. , Quality Control of 1-(Trifluoromethyl)-4-vinylbenzene, 402-50-6, Name is 1-(Trifluoromethyl)-4-vinylbenzene, molecular formula is C9H7F3, belongs to phthalazine compound. In a document, author is Wang Yinglei, introduce the new discover.
A novel poly(ethylene glycol) grafted 4-dimethylaminopyridine functionalized ionic liquid ([DMAP-PEG(1000)-DIL][BF4]) was prepared and characterized by H-1 NMR, C-13 NMR, FT-IR and ESI-MS. In the presence of [DMAP-PEG(1000)-DIL][BE4], various substituted aromatic aldehyde could react with malononitrile (or ethyl cyanoacetate) and phthalhydrazide in water to obtain a series of pyrazolo[1,2-b]phthalazine-5,10-dione derivatives with 85%similar to 96% yields. The mild reaction conditions, high stable and recyclable ionic liquids, environmental friendliness are advantages of this methodology.
