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.
