The synthesis and characterization of the novel 4,7-bis(dialkylamino)tricyclo[5.2.1.04,10]deca-1(10), 2,5,8-tetraenes 12 from 1,4,7-trihalotriquinacenes 8 and secondary amines is reported. The structural and electronic characteristics of these as well as the acepentalene dianion (32−) and some related systems as determined by semiempirical (MNDO) calculations are discussed. Thereby, 32− should be a
新型4,7-双(二烷基氨基)三环[5.2.1.0 4,10 ] deca-1(10),2,5,8-四烯12的合成和表征是由1,4,7-三卤代三对苯并二苯并[ 8]报道了胺。讨论了它们的结构和电子特性以及乙炔戊二酮(3 2-)和一些相关的系统,这些系统是通过半经验(MNDO)计算确定的。因此,3 2-应该是三价乙撑桥联的三亚甲基甲烷二阴离子,其表现出Y-离域作用,而不是形成外围的10π-电子系统。通过四烯12反应生成3 2-的尝试与Na的反应导致三(二烷基氨基)三喹并烷9的形成,大概是由于一种还原/歧化机理。
