The tris(pentafluoroethyl)silanol , Si(C 2 F 5 ) 3 OH, flashes out of the shadows of silanol derivatives in the cover image, paving the way to its disiloxane and disilanolate. Oxidation of tris(pentafluoroethyl)silane, Si(C 2 F 5 ) 3 H, with NO 2 provides Si(C 2 F 5 ) 3 OH, which readily condenses to disiloxane (C 2 F 5 ) 3 SiOSi(C 2 F 5 ) 3 . Deprotonation of in situ generated Si(C 2 F 5 ) 3 OH yields disilanolate [{Si(C 2 F 5 ) 3 O} 2 ] 2− underlining the formally Lewis amphoteric character of the monomeric tris(pentafluoroethyl)silanolate, [Si(C 2 F 5 ) 3 O] − .
