Summary:The developments of the catalytic, clean, and ecological decomposition of engineering polymers offer the possibility for new chemical recycle systems. Herein, we report that an aromatic polycarbosilane was completely decomposed by the treatment of 20 mol% TfOH-Air in crude toluene at room temperature to give biphenyl and silicone in quantitative yield. The decomposition of aromatic polycarbosilanes by trifluoromethanesulfonic acid involves the cleavage of the Si-C (sp2) bond.
