Abstract:

The dry sol-gel reaction at toluene in ambient air atmosphere of p-X-C₆H₄SiH₃ (X = H, CH₃, CH₃O, F, Cl) to p-C₆H₄SiO₃ in high yield, catalyzed by nickelocene, is reported. The highest yield, molecular weight, polydispersity index, and TGA residue yield were obtained for p-Cl-C₆H₄SiH₃. Some degree of unreacted Si-H bonds still remained in the gel because of steric reason. All the insoluble gels adopt an amorphous structure with a smooth surface. A plausible mechanism for the dry sol-gel reaction was suggested.
