Versuchsvorschrift
Procedure: To a solution of 1.23 g (0.006 mol) of N-(2-propynyl)carbazole in 19.2 mL of methanol 4.8 mL of water and 0.48 g of NaOH were added while stirring at 4° C. Addition of 6 mL of tetrahydrofurane (THF) to the turbid suspension resulted in a homogeneous solution. Then 1.52 g of crystalline iodine was added portion-wise. After 10 min of stirring the iodine color disappeared and the product started to separate as a dense white precipitate. Over 8 hrs of stirring at room temperature the product was filtered, washed with distilled water and air dried. 1.25 g (Yield 65%) of N-(3-Iodo-2-propynyl)carbazole has been obtained as crystals having m.p. 151-152° C. When applied onto a printing paper and analyzed according to Example 1, the compound gave an intense NIR FT-Raman spectrum in some features similar, but clearly not identical, to that shown in FIG. 1(A) for copper phenylacetylide (exemplary Compound #26 of the invention).
