Synthese und Eigenschaften von 1‐[Bis(trimethylsilyl)amino]‐borirenen

Abstract
Synthesis and Properties of 1‐[Bis(trimethylsilyl)amino]borirenesThe reaction of the 3‐[bis(trimethylsilyl)amino]‐1,2,3‐dithiaboroles 1a – f with sodium leads to ring contraction with formation of the hitherto unknown 1‐[bis(trimethylsilyl)amino]borirenes 2a – f. 1H, 11B, 13C, 29Si NMR spectra, IR and MS dates are reported.
