We describe efforts towards the synthesis of some allotropes of carbon, the cyclo[n]carbons where n= 18, 24 and 30. The key intermediate 11 is hexa-1,3,5-triyne with the central triple bond masked as a 1-amino-1,2,3-triazole derivative. Cyclo-oligomerisation of this by oxidative coupling gives macrocylic precursors of C18, C24, and C30. C30 is a proposed intermediate in the formation of C60 and we also describe some attempts at the synthesis of C60via the chemical generation of benzotryne, cyclo[6]carbon.
我们描述了合成某些碳同素异形体的努力,包括环状[n]碳(n=18、24和30)。关键中间体11是六烯-1,3,5-三炔,其中心的三重键被掩蔽为1-氨基-1,2,3-三唑衍生物。通过氧化偶联的环状低聚合可以得到C18、C24和C30的宏环前体。C30被提议为形成C60的中间体,我们还描述了一些通过化学生成苯三炔和环状[6]碳合成C60的尝试。
