実験手順

N-(3-Chloro-5,5-dimethylcyclohex-2-en-1-ylidene)-pyrrolidinium perchlorate (3.2 g.), dodecylsulfonylacetonitrile (2.7 g.) and triethylamine (3.1 ml.) are dissolved in ethanol (15 ml.) and heated at reflux for 5 minutes. After chilling, the solid is collected on a filter, washed with methanol and dried. Obtaining pure dye by recrystallization from methanol proved difficult. The product is eluted from basic alumina, using a 10% methanol-90% chloroform solvent mixture, and then recrystallized from methanol. The yield of purified dye is 0.5 g. (11%), m.p. 114°-115°C. This dye compound shows good ultraviolet absorption characteristics as indicated in the data in Table 1 below.
