Methods for their preparation have been elaborated. The structures have been studied on the basis of 1Н і 13С NMR spectra and X-ray diffractometry. It is found the planar structure of the carbene heterocyclic link with turning the phenylene nucleus by 30? relative to the triazole rings. The chemical transformations with sulfur and diphenyldiazomethane have been described. The complexes of copper (1), cobalt and praseodymium have been obtained on the basis of 1,3-bis-(1-adamantyl-4-phenyl-1,2,4-triazol-5-yliden-3-yl)benzene. The cobalt biscarbene complex undergoes hydrolytical transformation to form tetrachlorocobaltate of the respective bistriazolium salt. The results obtained have been submitted to an International journal of the speciality (a copy is attached). An account concerning the study is given, i.e. the methods for the preparation of bis/oligocarbenes and metal complexes on their basis Product Description popup.authors popup.nrat_date 2020-04-02 Close
