| Authors: | H Bürger D Beiersdorf |
| Abstract: | Cyclic Titanium Amides with Sila-titana-diazacyclobutane Structure N,N′ dilithiated diaminosilanes Me2Si(NHR)2, R = i-Pr, t-Bu and Me3Si, react with TiCl4 in a 2:1 ratio to form spirocyclic titanium amides ( B, C 1 ; see Inhaltsübersicht). In a 1:1 ratio or upon reaction with (R′2N)2TiBr2, R′ = Me, Et, titanacyclobutanes ( C 2—C 6 ) are obtained. Compounds with R = Me3Si exhibit particularly high thermal stability. |
