for site‐selectivefunctionalization of unactivated methylene and methine C−H bonds enabled by an FeII‐catalyzed redox process is described. The mild, expeditious, and modular protocol allows efficient remote aliphatic fluorination, chlorination, amination, and alkynylation of structurally and electronically varied primary, secondary, and tertiary hydroperoxides with excellent functional‐group tolerance
The γ-radiolysis of 2-propanol solutions of cyclohexanone gives mainly hydrogen, acetone, pinacol, methane derived from 2-propanol, and cyclohexanol, 2-(2-cyclohexanonyl)-cyclohexanone, and 3-(2-hydroxy-2-propyl)cyclohexanone derived from cyclohexanone. The radiolytic yields of all these products were highly dependent on the initial cyclohexanone concentration. The formation of cyclic alcohols by radioreduction
A method for producing a carbonyl compound of the present invention comprises a step (X) of reacting a specific compound having a urea bond with a carbonic acid derivative having a carbonyl group (—C(═O)—) under heating at a temperature equal to or higher than the thermal dissociation temperature of the urea bond to obtain the carbonyl compound.

Disclosed is a process for preparing an aryloxyalkylene amine compound via an aminoethylation reaction comprising: a) reacting an aromatic hydroxyl compound in the presence of a basic catalyst with a 2-oxazolidinone compound of the formula II to form an intermediate reaction product;
wherein R
3
is selected from the group consisting of hydrogen or lower alkyl having 1 to 6 carbon atoms, R
4
is selected from the group consisting of hydrogen, straight or branched chain alkyl having from one to six carbon atoms, phenyl, alkaryl, or arylalkyl; and b) reacting the intermediate product of step a) with a polyalkylene polyamine.
