the counterion (I−, BF), a reductive cleavage of the N(1)–C(8a) bond (photo-Emde degradation). The corresponding N,N-dimethyl-3-phenylpropylamines are formed in high yields and without contamination by Hofmann degradation products of the tetrahydroquinolinium salts. Me groups at C(2) as well as substituents at C(6) (CH3, Cl, CH3O) favour the photo-Emde degradation. The aromatic Cl-substituent is reductively
结果表明,1,1-二甲基-1,2,3,4- tetrahydroquinolinium离子经历,直接照射下通过在CH石英3 OH和独立的平衡离子的性质(I -,BF),的还原裂解N(1)–C(8a)键(光Emde降解)。以高收率形成相应的N,N-二甲基-3-苯基丙胺,而没有被四氢喹啉鎓盐的霍夫曼降解产物污染。C(2)处的Me基团以及C(6)处的取代基(CH 3,Cl,CH 3 O)有利于光Emde降解。在光反应过程中,芳族Cl-取代基被还原分离。
