Intramolecular N,N-coupling by the electrochemical oxidation of cyclic and open-chain diamines such as 3,3,7,7-tetraethylperhydro-1,5-diazocine (1) and N,N-dimethyl-2,2-diethyl-1,3-diaminopropane (2) was investigated with the use of platinum, silver, nickel, and carbon anodes. In the case of 1, cyclic hydrazine derivatives, 3,3,7,7-tetraethyl-1,5-diazabicyclo[3.3.0]octane and 1-(2-ethyl-2-formylbutyl)-4
通过环状和开链二胺(例如 3,3,7,7-四乙基全氢-1,5-二氮辛 (1) 和 N,N-二甲基-2,2-二乙基-)的电化学氧化进行分子内 N,N-偶联使用铂、银、镍和碳阳极对 1,3-二氨基丙烷 (2) 进行了研究。在1,环状肼衍生物的情况下,3,3,7,7-四乙基-1,5-二氮杂双环[3.3.0]辛烷和1-(2-乙基-2-甲酰基丁基)-4,4-二乙基- 4,5-二氢吡唑,在高电流效率下形成。在2的情况下,相应的肼,1,2-二甲基-4,4-二乙基吡唑烷和1-甲基-3,3-二乙基-4,5-二氢吡唑,在低电流效率下获得,因为C-N键解理发生在 N,N 偶联之前。发现碳阳极对于此类二胺的 N,N-偶联有效。化学氧化氮,
