碗形苏蔓烯(1)与K金属的2倍去质子化使在[2.2.2]隐式和18冠-6醚存在下结晶的苏蔓烯基二离子与相应的钾(I)反离子接触。对[{K+([2.2.2]cryptand)}2(C21H102 -)](2)的x射线晶体学研究表明,[{K+(18-crown-6)}2(C21H102 -)](3)中,两个K+离子结合在碗的外表面。详细的结构分析证实,在c21h102的非平面碳骨架中形成了两个类cp环,作为碱金属配位的位置。
The controlled 2-fold deprotonation of bowl-shaped sumanene (1) with K metal provides access the sumanenyl dianion that was crystallized in the presence of [2.2.2]cryptand and 18-crown-6 ether with the corresponding potassium(I) counterions. The X-ray crystallographic study of [{K+([2.2.2]cryptand)}2(C21H102–)] (2) revealed the formation of a “naked” sumanenyl dianion, while in [{K+(18-crown-6)}2(C21H102–)] (3) two K+ions bind to theexo-surface of the bowl. The detailed structural analysis confirms the formation of two Cp-like rings embedded into a nonplanar carbon framework of C21H102–serving as sites for alkali metal coordination in3.
