Synthesis of high-electron donating 1,3-di(1-adamantyl)-4,5-dihydroimidazol-2-ylidene, 1,3-di(1-adamantyl)-5,6-dihydro-4H-pyrimidin-2-ylidene, stable complexes of superbasic carbene 1,3-bis-(4-oxidophenyl)imidazole-2-ylidene and nickel, 2-oxidophenyl-1,2,3-triazole-5-ylidene complexes of titanium and tin, fluoro substituted 1,2,4-triazol-5-ylidene and their carbene complexes with copper(I) and palladium iodides. Significant catalytic effect of the synthesized carbenes in the reaction of hydrodehalogenation of p-dichlorobenzene with isopropanol by alkali metal formates at 80 °C (TON to 790), the reaction of cyanodehalogenation of halorenes (TON to 1000) and trifluoromethyldehalogenation (TON to 99). The area of application is the synthesis of stable carbenes and their carbenoid forms, the catalysis of organic reactions, the neutralization of persistent organic pollutants.
