Al-Rubaie, Ali Z. published the artcilePalladium-catalyzed formation of 3,5-diaryl-1,2,4-selenadiazoles from arylselenocarboxamide, COA of Formula: C9H9NO2, the main research area is diarylselenadiazole preparation; arylselenocarboxamide preparation cyclization; selenadiazole diaryl preparation.
A number of new and known arylselenocarboxamides RC(:Se)NH2 [R = Ph, 4-BrC6H4, 2-MeOC6H4, 4-MeOC6H4, 4-MeSC6H4, 4-EtOC6H4, 2,3-(MeO)2C6H3, 3,4-(MeO)2C6H3, 3,5-(MeO)2C6H3, 4-PhC6H4, 6-MeOC10H6, 4-MeOC10H6] have been prepared in high yields by the reaction of RCN with NaHSe. Treatment of RC(:Se)NH2 (4 mmol) with aqueous Na2PdCl4 (1 mmol) in acetone at room temperature resulted in the formation of 3,5-diaryl-1,2,4-selenadiazoles (L) as unexpected products together with palladium(II) complexes [PdCl2L]2.2H2O. Treatment of RC(:Se)NH2 (4 mmol) with catalytic amounts of Na2PdCl4 (10-3 mmol) gave only 3,5-diaryl-1,2,4-selenadiazoles in good yields. 3,5-Diaryl-1,2,4-selenodiazoles were also prepared by oxidation of arylselenocarboxamides with iodine for comparison.
Journal of Organometallic Chemistry published new progress about diarylselenadiazole preparation; arylselenocarboxamide preparation cyclization; selenadiazole diaryl preparation. 5653-62-3 belongs to class nitriles-buliding-blocks, name is 2,3-Dimethoxybenzonitrile, and the molecular formula is C9H9NO2, COA of Formula: C9H9NO2.
