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 ...
