Novel synthesis of 1,4-diazacrown ethers by reductive coupling of aromatic diimines
摘要:
The electroreduction or chemical reduction with zinc powder has been found to be effective to intramolecular coupling of aromatic diimines yielding 1,4-diazacrown ethers. The latter reduction was particularly effective to formation of 1,4-diaza-12-crown-4 derivatives due to the template effect of Zn2+.
