-
Paragraph 0046-0048, (2020/07/28)
The invention discloses a novel synthesis method of benzothiacyclopentadiene, and belongs to the technical field of synthesis. The method comprises the following steps that: under an alkaline condition, chloroacetaldehyde and thiophenol undergo a Williamson condensation reaction to obtain thiophenyl acetaldehyde, the thiophenyl acetaldehyde undergoes a cyclization and dehydration reaction with a dehydrating agent under an acidic condition, water is added, layering is performed, an organic layer is taken, and reduced pressure distillation is performed to obtain the target product benzothiacyclopentadiene. The method has the advantages of simple operation, mild reaction, easy realization of industrialization, and high product yield.
