Provided is a low reflection glass excellent in the abrasion resistance, the weather resistance, the productivity and the outer appearance, and a protective plate for a display. A low reflection glass includes a glass substrate and an antireflection film formed on the surface of the glass substrate. The antireflection film comprises an interlayer and an outermost layer in this order from the glass substrate side; and the outermost layer is a layer containing Si atoms, C atoms and O atoms. The content of C atoms is from 0.5 to 3 mol % based on 100 mol % of the total amount of Si atoms, C atoms and 0 atoms. The interlayer is a layer (a) (high refractive index layer) or a layer (b) (light absorbing layer). A protective plate for a display comprises a support substrate comprising the low reflection glass and a conductive film provided on a side on which no antireflection film is formed of the support substrate.

Low reflection glass and protective plate for display

It is to provide a process for synthesizing an intended fluorine-containing compound having a geminal difluoro structure with a high yield, by subjecting a carbonyl compound which is readily available to a two-stage reaction. A compound (1) such as ethyl 4-oxocyclohexanecarboxylate is reacted with a compound of the formula X-Z or a compound of the formula ZO (wherein Z is a monovalent group which gives a leaving group of the structure &#x2014;OZ, and X is a chlorine atom, a bromine atom or an iodine atom) such as phosphorus pentachloride, and then a fluorinating agent which generates fluorine anions such as HF is acted thereon to obtain a fluorine-containing compound (2) such as ethyl 4,4-difluorocyclohexanecarboxylate
