Aryldiazoacetates can undergo photolysis under blue light irradiation (460–490 nm) at room temperature and under air in the presence of numerous trapping agents, such as styrene, carboxylic acids, amines, alkanes and arenes, thus providing a straighforward and general platform for their mild functionalization.

Abstract An efficient procedure has been developed for the synthesis of secondary amides by the Ritter reaction of cage substrates with a wide series of nitriles in fuming nitric acid and its mixtures.
Tri-2-furylgermane proved to be an effective reagent for the radical reduction of organichalides. Treatment of 1-bromododecane with tri-2-furylgermane in THF at 25 °C in the presence of a catalytic amount of triethylborane afforded dodecane almost quantitatively. Radical cyclization of 2-iodoethanal allyl acetal afforded five-membered products under the same reaction conditions. These reactions proceeded

RuCl3 successfully reacts with the lacunary silicotungustate in organic medium, giving a Ru3+-substituted silicotungstate that can act as a heterogeneous catalyst for the oxidation of a wide range of alkanes and alcohols using 1 atm of molecularoxygen as the sole oxidant.
oxyalkylated products in 91% yield. Other alkenes such as fumarate and acrylonitrile also serve as good acceptors of alkylradicals and O(2) to afford the corresponding adducts in high yields. The generality of the present reaction was examined between various alkanes and alkenes under dioxygen. The behavior of Co ions during the reaction course was discussed. The present reaction involves (i) an alkyl radical
