摘要: Abstract N,N-Dimethyl-o-toluidine, N,N-dimethylaniline, and N,N-diethylaniline were treated with n-butyllithium-tmeda in diethyl ether–hexane solution to give o-lithioarylamines, which react various electrophiles (benzophenone, dicyclohexyl ketone, benzaldehyde, Ph(H)CNPh) form the corresponding (2-dialkylaminophenyl)alcohols 1-HOCPh2-2-NMe2C6H4 ( 1 ), 1-HOCCy2-2-NMe2C6H4 2 1-HOCPh2CH2-2-NMe2C6H4 4 1-HOC(H)PhCH2-2-NMe2C6H4 6 1-HOCPh2-2-NEt2C6H4 7 2-phenylaminoalkyl-dimethylaminobenzene derivatives 1-NMe2-2-NH(Ph)C(H)PhC6H4 3 ) 1-NMe2-2-NH(Ph)C(H)PhCH2C6H4 5 ). Compounds 1–7 characterized spectroscopically (NMR, IR, MS) by crystal structure determination.
