A method for the synthesis of 5-aryl-1,3,3,-trimethyl-2-methylene-indoline derivatives of Formula (I) or its salts of Formula (Ia)
1
wherein 1 mole of a 5-aryl-2,3,3-trimethyl-3H-indole derivative of Formula (VII) is reacted for 1 to 44 hours at a temperature of 20° to 180° C. in an apolar, aprotic or polar, protic or polar aprotic solvent with 1 to 50 moles of a compound of Formula R1-A; new compounds of Formulas (I)/(Ia) and (V), obtainable by this method
2
as well as an agent containing at least one compound of Formula (I)/(Ia) and a carbonyl/inune compound for dyeing keratinic fibers and a method for temporarily dyeing keratin fibers, for which the keratin fiber is dyed with the aforementioned agent and the dyeing, so obtained, is removed again at any later time by a sulfite preparation.
一种合成式(I)的5-芳基-1,3,3-三甲基-2-亚甲基吲哚衍生物或式(Ia)的盐的方法,其中1摩尔的式(VII)的5-芳基-2,3,3-三甲基-3H-吲哚衍生物在无极性,无质子或极性,质子或极性无质子溶剂中与1至50摩尔的式R1-A的化合物在20℃至180℃的温度下反应1至44小时;通过该方法获得的新化合物包括式(I)/(Ia)和(V);以及一种含有至少一种式(I)/(Ia)化合物和用于染色角质纤维的羰基/不饱和化合物的制剂和一种暂时染色角质纤维的方法,其中将角质纤维染色剂染色,所得的染色可以在以后的任何时候通过亚硫酸盐制剂去除。
