摘要
[14976-80-8] C4H8CrO5 (MW 188.12)
InChI = 1S/2C2H4O2.Cr.H2O/c2*1-2(3)4;;/h2*1H3,(H,3,4);;1H2/q;;+2;/p-2
InChIKey = BUGMCLNOCJDESP-UHFFFAOYSA-L
(capable of reducing reactive carbon–halogen bonds (e.g. allylic, benzylic, α-halo carbonyl);1 bromohydrins2 and epoxides;3 used in the conversion of ketoximes to ketones4 in the presence of acid- and base-sensitive functional groups)
Physical Data: d 1.79 g cm−3.
Solubility: slightly sol cold water; readily sol hot water; sol in and reacts with most acids; slightly sol alcohol; practically insol ether.
Form Supplied in: deep red powder or monoclinic crystals; composed of dimeric units.
Drying: loses water when dried over P2O5 at 100 °C, changing color to brown.
Handling, Storage, and Precautions: easily oxidized, especially when moist, to chromium(III) acetate. It can be stored for several months in a stoppered vial under carbon dioxide.
