C6H2−2,4,6-Cyp3, affords an equilibrium mixture of the distannene Sn(C6H2−2,4,6-Cyp3)2}2, and cyclotristannane Sn(C6H2−2,4,6-Cyp3)2}3, which suppresses monomer dissociation. Multinuclear NMR and computational analyses indicated that DED interactions are the main arbiter of the dimer-trimer thermal interconversion.
使用分散能量供体 (DED) 配体 C 6 H 2 −2,4,6-Cyp 3提供了二锡烯Sn(C 6 H 2 −2,4,6-Cyp 3 ) 2的平衡混合物} 2和环三烷烷Sn(C 6 H 2 -2,4,6-Cyp 3 ) 2 } 3,其抑制单体解离。多核 NMR 和计算分析表明 DED 相互作用是二聚体-三聚体热互变的主要决定因素。
