1,3-Bis[tert-butyl(di-tert-butylfluorosilyl)amino]trisulfane – a Compound with FSiNSSSNSiF Helix
The lithium derivative of tert-butyl(di-tert-butylfluorosilyl)-amine (1) reacts with sulfur or selenium to give the bis[(fluorosilyl)-amino]di- and -trisulfanes 2, 3 and -selane 4, respectively. The trisulfane 3 crystallizes from n-hexane and exhibits a helical structure (X-ray analysis).read more
