METHOD OF N-VINYLCARBAZOLE SYNTHESIS Russian patent published in 1994 - IPC

Abstract SU 1536761 A1

FIELD: organic chemistry. SUBSTANCE: synthesis is carried out by vinylation of carbazole with acetylene in the presence of potassium hydroxide and dimethylsulfoxide at heating. Process is carried out at 70-90 C in the presence of 1-3% water of reaction mixture mass following by washing of product formed with 1-5% potassium hydroxide solution at 50-60 C. Method ensures to carry out the process decreasing temperature by 10-60 C. Synthesized product is used as monomer for synthesis of organic polymeric semiconductors. EFFECT: simplified process.
