Abstract
The functional polycarbosilane [Si(X 2)C2H4] n , whereX 2=Cl2 (1), was chemically transformed into the corresponding polymers, whereX 2=F2 (3), (2-N, N-dimethylbenzylamino)(H) (5), (9-N,N-dimethyl-1-naphthylamino)(H) (6), (1-C10H7)(H) (7), Me2 (8a), (Me3SiNH)2 (10), and (vinyl)(H) (11). The functional polycarbosilane, whereX 2=H2 (2), was converted into the polymers, whereX 2=Me(H) (8b) and (OMe)2 (9). Reaction of3 with KF in the presence of 18-crown-6 gave rise to the poycarbosilane4 containing both pentacoordinate and tetracoordinate silicons in the proportion of 1:15 as shown by quantitative19F and29Si NMR. Conversion of a greater proportion of silicon atoms to the pentacoordinate state was not possible because of insolubility of the resulting ionomer in the reaction medium.
