Abstract:
A visible light active photodegration catalyst was prepared by doping MoO(3) into MgF(2) matrix. The addition of SO(4)(2-) into MoO(x)/MgF(2) could improve the catalytic activity greatly and an acetone conversion of 96.1% under visible light was obtained on the SO(4)(2-)/5%MoO(x)/MgF(2) (SMM) catalyst. By BET, XRD, Raman, FT-IR, XPS, UV-vis technology the specific area, structure and photoadsorption ability of the catalysts were characterized. The high photocatlaytic activity of the SMM catalyst is attributed to its large specific area, the high dispersal of MoO(3) domains in MgF(2) and the inhibiting effect of MgF(2) matrix on the electron-hole pair recombination.

Oxidations of Aldehydes and Ketones to Carboxylic Acids
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
