Indium-Catalyzed Reductive Dithioacetalization of Carboxylic Acids with Dithiols: Scope, Limitations, and Application to Oxidative Desulfurization

In this study an InI3-TMDS (1,1,3,3-tetramethyldisiloxane) reducing system effectively catalyzed the reductive dithioacetalization of a variety of aromatic and aliphatic carboxylic acids with 1,2-ethanedithiol or 1,3-propanedithiol leading to the one-pot preparation of either 1,3-dithiolane derivatives or a 1,3-dithiane derivative. Also, the intact indium catalyst continuously catalyzed the subsequent oxidative desulfurization of an in situ formed 1,3-dithiolane derivative, which led to the preparation of the corresponding aldehydes.

Process for production of 1,4-bis(difluoroalkyl)benzene derivative

A process is provided which allows a 1,4-bis(difluoroalkyl)benzene derivative to be produced inexpensively by a simple procedure without requiring any special facility. This process comprises causing a compound (A) of the following formula (1): wherein X1, X2, X3, and X4 independently stand for an oxygen or sulfur atom, Y1 and Y2 independently stand for a group of the formula: —CnH2n—, in which n is 2 or 3, k is an integer in the range of 0 to 4, G stands for a halogen group, an alkyl group, a perfluoroalkyl group, or an alkoxy group, and m is an integer in the range of 0 to 4, to react with a fluorine-containing species, the molar ratio of the fluorine-containing species to compound (A) being in the range of 20-40. The process is carried out in the presence of a bromine-containing compound, which is in an amount of 2 to 3 equivalences to the amount of compound (A), in an organic solvent at ?80° C. to 30° C., the final concentration of compound (A) being in the range of 3 to 30% by weight.
