The preparation of N,N′-dialkyl- and N,N′-diaryl-1,6-diazacyclodeca-3,8-diynes was achieved by reaction of alkyl- or arylamines with 1,4-dihalobut-2-yne under dilution conditions in yields of 5–15%. The compounds synthesized by this procedure were the N,N′-dimethyl (2b), N,N′-diethyl (2c), N,N′-diisopropyl (2d), N,N′-di-tert-butyl (2e), N,N′-dicyclohexyl (2f), N,N′-diphenyl (2g), and N,N′-di-p-tolyl
的制备Ñ,Ñ ' -二烷基和Ñ,Ñ '-diaryl -1,6- diazacyclodeca -3,8-二炔物通过的烷基-芳基胺或与反应下稀释1,4- dihalobut -2-炔实现产量为5%至15%。通过该方法合成的化合物是所述Ñ,Ñ ' -二甲基(图2b),Ñ,Ñ ' -二乙基(图2c),Ñ,Ñ '二异丙基(2D),Ñ,Ñ ' -二-叔丁基(2E),N,N′-二环己基(2f),N,N′-二苯基(2g)和N,N′-二-对甲苯基(2h)衍生物。大约在2小时内获得母体化合物2a。通过与α-氯乙基氯甲酸酯(20)加热2天,产率为40%。分别使用1,9-二溴monona-2,7-二炔(10)和甲胺或异丙胺,在稀释条件下合成了相应的N-烷基-1-氮杂环癸-3,8-二炔4b和4d。用20加热4d我们获得了1-氮杂环癸3,8-二炔(4a)。分离并表征了三聚体18和四聚体12和19作为环化反应的副产物。通过使1
