Novel [2.2]paracyclophane derivatives via charge-transfer complexation

摘要: The transannular electronic interactions in [2.2]paracyclophanes affect the selectivity of tricyanovinylation reaction with tetracyanoethylene (TCNE). In addition to normal N-tricyanovinyl product, 4-amino[2,2]paracyclophane reacts TCNE give oxaziridine derivatives. case 4-N-methylamino[2.2]paracyclophane, unusual N-tricyanovinylated product as well 4-(N-carbonitrile-N-methyl)annino[2.2]paracyclophane was isolated. 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) 4-amino[2.2]paracyclophane results formation 2-cyano-3-(4-[2.2]paracyclophanyl)amino-5,6-dichloro-1,4-benzoquinone.
