Trapped in action: The amine‐induced disproportionation of Si2Cl6 or Si3Cl8 to neo‐Si5Cl12 and SiCl4 involves a SiCl2–base adduct as a key intermediate (see scheme). Direct evidence from low‐temperature 1H/29Si HETCOR NMR and trapping experiments with dimethylbutadiene together with detailed mechanistic information derived from theory provide a clear view on the principles of this intriguing reactivity
被困:胺引起的Si 2 Cl 6或Si 3 Cl 8歧化为neo- Si 5 Cl 12和SiCl 4涉及作为主要中间体的SiCl 2基加合物(参见方案)。低温1 H / 29 Si HETCOR NMR的直接证据以及二甲基丁二烯的捕集实验以及从理论得出的详细机理信息,为这种有趣的反应原理提供了清晰的认识。
