摘要：NOVELTY - The present invention is new type of diphenyl acetenyl silane synthesizing process. By using phenyl acetylene, organic lithium reagent and methyl dichlorosilane as material and anhydrous tetrahydrofuran as solvent, the present invention synthesizes methyl diphenyl acetenyl silane monomer through two-step reaction. Phenyl acetylene and butyl lithium first react to produce phenyl acetenyl lithium, and phenyl acetenyl lithium and hydrogen-containing dichlorosilane then react to produce phenyl acetenyl silane. The present invention has simple technological process, simple and feasible operation, short reaction time, controllable reaction condition, high product yield and purity and other advantages, and is suitable for industrial production. The prepared diphenyl acetenyl silane may be used inhigh performance composite material, ceramic precursor, heat resistant coating, etc.
