Asymmetric ditertiary stibine sulfides (C6H5)(CH3)(S)SbCH2Sb(CH3)(C6H5) and [(C6H5)(CH3)(S)Sb]2(CH2)3 have been prepared. It was found that they exist as only one of two possible diastereomers in the crystalline state. However, isomerization to the other form takes place in solution, resulting in an equilibrium mixture. A possibility of configurational lability of tertiary stibine sulfide was suggested
不对称二叔丁基硫化氢(C 6 H 5)(CH 3)(S)SbCH 2 Sb(CH 3)(C 6 H 5)和[(C 6 H 5)(CH 3)(S)Sb] 2(CH 2)3已经准备好。发现它们仅以两种可能的非对映异构体形式存在于结晶状态。然而,异构化成另一种形式在溶液中发生,导致平衡混合物。首次提出叔丁基硫化氢的构型不稳定性的可能性。
