摘要:
Azoamide compounds shown by the general formula [1] (Wherein R 1 and R 2 are independently a lower alkyl group, and R 3 is a saturated alkyl group having 2 or more carbon atoms) and their use.
摘要:
The invention concerns a method for preparing an azoiminoether hydrochloride which consists in reacting an azonitrile with an alcohol and hydrochloric acid in an aromatic solvent, wherein the molar ratio R = HCl/azonitrile is > 2 when the alcohol is methanol and > 3 when the alcohol is ethanol or a higher alcohol. The invention also concerns a method for preparing an azocarboxylic acid ester which consists in the synthesis of an azoiminoether hydrochloride by the inventive method and, hydrolysis in the presence of the resulting azoiminoether hydrochloride. Said methods enable to obtain liquid composition of azocarboxylic acid esters. The invention further concerns mixed azoiminoether salts of formula (II'). The invention also concerns mixed azoiminocarboxylic acid esters corresponding to the formula (III').

A compound shown by the general formula [1] wherein R 1 and R 2 are independently a Lower alkyl group or a cyano group, R 3 is a lower alkyl group and X is a lower alkylene group, showing high solubility into various kinds of polar solvents and are capable of effectively introducing hydroxy groups into terminal positions of polymers and their use.
摘要:
An azoamide compound of the formula: wherein R 1 through R 4 are independently an alkyl group; X is an alkylene group; Y is -O- or -NH-; and n is an integer of 2 or more, is effective for producing a macroazo compound, which is a useful initiator for producing block copolymers.
摘要:
A process for the production of fluorinated organic compounds, characterized by fluorinating an organic compound bearing a hydrogen atom with IF5; and a novel fluorination process of fluorinating an organic compound bearing a hydrogen atom by using a fluorinating agent containing both IF5 and at least one member selected from the group consisting of acids, bases, salts and additives.
