摘要：
3-Aryl-1,2,4,5-tetrazines 1a-d were lithiated with lithium 2,2,6,6-tetramethylpiperidide and the formed lithio-1,2,4,5-tetrazines trapped with aldehydes or benzophenone to give 3-aryl-6-(alpha-hydroxymethyl)-1,2,4,5-tetrazines 2a-h. Side-products of these reactions are 3-aryl-6-(2,2,6,6-tetramethylpiperidyl-1)-1,2,4,5-tetrazines 3a, c, d and 1-aryl-4-(6-aryl-1,2,4,5-tetrazinyl-3)-2,3-diazabutadienes 4a-d.
