The catalytic transesterification was effected under the influence of carbenes of the benzimidazole, 1,2,4-triazole and bis-1,2,4-triazole series. The data about biological activity of the carbenoids synthesized were also obtained. 3 reports on the scientific conferences, 2 papers in the international journals and 1 paper in the Ukrainian journal were published, 1 paper was sent to press. An account concerning the study is given, i.e. the methods for the preparation of craun bisarbenoid and craun catalytic transesterification.
