solvent-free oxidation of alcohols, which proceeds efficiently under solid–solid (liquid)–gas conditions, was developed. Various primary and secondary alcohols were transformed to corresponding aldehydes and ketones in moderate to excellent isolated yields by simply stirring in the presence of 10% Ru/C under air or oxygen conditions. The solvent-free oxidation reactions proceeded efficiently regardless of the

A catalyst includes a cyclic imide compound having an N-substituted cyclic imide skeleton represented by following Formula (I):
1
wherein X is an oxygen atom or a hydroxyl group, and having a solubility parameter of less than or equal to 26 [(MPa)
½
] as determined by Fedors method. The catalyst may further comprise a metallic compound. By allowing (A) a compound capable of forming a radical to react with (B) a radical scavenging compound in the presence of the catalyst, an addition or substitution reaction product between the compound (A) and the compound (B) or a derivative thereof can be obtained.

A new synthetic route to 3,4-bridged 1,6,6aλ 4-trithiapentalenes is developed based on reactions of cyclic ketones with Bredereck's reagent followed by thiolation of keto dienamines with phosphorus pentasulfide or Lawesson's reagent.
Provided is a method of oxidizing a substrate with excellent oxidizing power to yield a corresponding oxide. The method can employ a commercially available imide compound as intact as a catalyst and can produce the oxide in a high yield under mild conditions.
A method for producing an oxide according to the present invention includes performing oxidation of a substrate in the presence of oxygen and ozone under catalysis of an imide compound to yield a corresponding oxide. The imide compound has a cyclic imide skeleton represented by Formula (I). In the formula, n is selected from 0 and 1; and X is selected from an oxygen atom and an —OR group, where R is selected from hydrogen and a hydroxy-protecting group.
