5-aryl-1,3,3-trimethyl-2-methylene - indoline derivatives and salts thereof, used for temporary textile dyeing of their preparation and these compounds

摘要

A process for the preparation of salts (Ia) of this formula or indoline derivatives, - the following formula (I) 5- aryl 1,3,3-trimethyl-2-methylene- [Formula 1] At a temperature of 20~180 ℃, the following formula (VII) 5- aryl 2,3,3-trimethyl -3H- indole derivative 1 mole of polar and non-polar or-protic or non-polar, aprotic method is characterized in that a solvent of protic, and is converted over 1-44 hours using a compound of formula R1-A 1 to 50 molar; formula obtained by this step (I) / (Ia) and novel compounds represented by (V); [23] of And stained with the drug the keratin fibers and agents, the keratin fibers for dyeing, which contains at least one carbonyl compound / imine compound and one of the compounds of the formula (I) / (Ia), any further after process for the temporary dyeing of keratin fibers bleaching restored by sulfite-containing formulations this staining at the time.
