The International Union of Pure and Applied Chemistry (IUPAC) name given in the title is incorrect. The correct IUPAC name for this molecule is tetraspiro[2.1.25.1.29.1.213.13]hexadecane‐4,8,12,16‐tetraone. The incorrect name given in the title, unfortunately, makes the carbon atom hexavalent at two different (3 and 5) positions. In addition, the two other keto groups (at positions 1 and 7) would appear on two of the cyclopropane rings if one adopts to the incorrect name. Nevertheless, this wrong name is a good example to discuss the importance of IUPAC nomenclature in the classroom with students.

关于“超越二聚体和三聚体：四螺[2.1.25.1.29.1.213.13]十六烷-1,3,5,7-四酮——羰基环丙烷的环状四聚体”的通讯


标题中给出的国际纯粹与应用化学联合会 (IUPAC) 名称不正确。该分子的正确 IUPAC 名称是四螺[2.1.25.1.29.1.213.13]十六烷-4,8,12,16-四酮。不幸的是，标题中给出的错误名称使碳原子在两个不同的位置（3 和 5）成为六价。此外，如果名称不正确，另外两个酮基（位置 1 和位置 7）将出现在两个环丙烷环上。尽管如此，这个错误的名称是一个很好的例子，可以在课堂上与学生讨论 IUPAC 命名法的重要性。
