As the catalyst, No. Heterocyclic yield (%) ratio (a: b) with the electronic structure and the various different aliphatic amines / epoxy aromatic compounds open loop. (Table 2, points were recorded 1-23) 0.18 aniline and the reaction of styrene oxide provides the joint production of 92% [2 - (aniline) - 2 - Phenylethanol + 2 - (benzene - 2 ylamino ) - 1 - phenyl ethyl], the main isomer has an excellent regional selectivity, as many as 84 percent. Isomers of the main structure by the 3 M +1 GC-MS (base-31) and H nuclear magnetic resonance (dd, d = 3.65 ppm, hydrogen p-nuclear) confirmed that the attack in the benzyl position with I.19 For electronic-based and electronic four-absorption of aniline, for example, Me, OMe, CF3, F (recorded at 2-5) in the current catalytic system and well tolerated. With a large number 2 - naph-5 thyl amine of styrene effective solution of ammonia to 88% of the yield (recorded 6 points). Dihydroindol-oxide and styrene is a very short response time smooth
