Abstract:Silaethene lassen sich in Losung durch Eliminierungsreaktionen vom Typ (la) + (I b) erzeugen und als [2 + 21-Cycloaddukte nachweisen['l. X = elektronegativer Substituent, M = Alkalimetall
“…The 29 Si NMR spectrum of 2 shows the resonance signal at 33.3 ppm, which can also be consistent with the data of the silene IV and is in the range of signals of an imine adduct of a silene described by Wiberg [9] or a silaketimine synthesized by Kira [10]. Comparable silenes of silyl-hydrazones were obtained and characterized as dimers via the Si@C-bond [11][12][13].…”
“…The space group of 6 is triclinic, P 1, with unit-cell dimensions a = 1012.21 (12), b = 1250.28 (18), c = 1316.78(18) pm, a = 77°(11), b = 89.85°(10), c = 88.79°(11), u = 1.626(4) nm 3 , Z = 1.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
