Zusammenfassung

Tetrakis(2-fluorophenylamino)silan (1) wurde als Precursor zur Darstellung poröser, nitridischer Festkörper synthetisiert und mit Hilfe der Einkristallröntgenstrukturanalyse charakterisiert (C2/c;a=16.771(7) Å,b=16.827(5) Å,c=16.753(6) Å, ß=111.00(2)°,z=8). Beim Erhitzen mit Ammoniumcarbamat als Katalysator wurde N-(2-fluorophenyl)-Si, Si, Si, Si′, Si′, Si′, -hexakis(2-fluorophenylamino)disilazan (2) als erstes Kondensationsprodukt isoliert (\(P\bar 1\);a=9.331(1) Å,b=13.698(5) Å,c=16.164(4) Å, α=90.34(2)°, ß=103.03(2)′, γ=103.04(3)°, Z=2).

Summary

The synthesis and crystal structure determination of silanetetramine N,N′,N″,N‴2-fluorophenyl(C2/c;a=16.771(7) Å,b=16.827(5) Å,c=16.753(6) Å, ß=111.00(2)°, z=8) are reported. In a search for suitable condensation pathways to silicon/nitrogen based porous solids, N-(2-fluorophenyl)-Si,Si,Si,Si′,Si′,Si′-hexakis(2-fluorophenylamino)disilazane (2) has been obtained from the ammonium carbamate catalyzed condensation of the silanetetramine in teflon lined autoclaves. The X-ray crystal structure determination (\(P\bar 1\);a=9.331(1) Å,b=13.698(5) Å,c=16.164(4) Å, α=90.34(2)°, ß=103.03(2)°, γ=103.04(3)°, Z=2) shows the disilazane to be a dimer formed by linear condensation from the monomeric silazane.
