WebStudien N-heterozyklischer Olefine als Donoren in Triarylboranen und Elektronenarmer Phenylpyridyl-fusionierter Borole Please always quote using this URN: urn:nbn:de:bvb:20-opus-217175 Jiang He Chapter 1 N-Heterocyclic olefins (NHOs), relatives of N-heterocyclic carbenes (NHCs), exhibit high nucleophilicity and soft Lewis basic character. WebAbstract. (Hetero)arene-fused boroles are a class of compounds containing a 5-membered boron diene-ring. Based on their molecular framework, the (hetero)arene-fused boroles can be considered as boron-doped polycyclic antiaromatic hydrocarbons and are thus of great interest. Due to the vacant p z orbital on the 3-coordinate boron atom, the ...

WebJUST PUBLISHED IN ANGEWANDTE CHEMIE: Phenylpyridyl‐Fused Boroles: A Unique Coordination Mode and Weak B−N Coordination‐Induced Dual Fluorescence — Dr. Jiang He, Dr. Florian Rauch, Dr. Alexandra... Phenylpyridyl-fused boroles [TipPBB1]4 and TipPBB2 were synthesized and their properties investigated. [TipPBB1]4 forms a tetramer in both the solid state and solution. TipPBB2 contains a 4-coordinate boron atom in the solid state but dissociates to give a 3-coordinate boron species in solution. WebAbstract. Two derivatives of phenylpyridyl-fused boroles were prepared via functionalization of the pyridyl groups, namely to an electron-rich dihydropyridine moiety (compound 1) and … bilton road dentist
