A simple and facile method for the synthesis of aromatic tertiary amines by amination of fluoroarenes with secondaryamines in the presence of n-butyllithium at room temperature was reported.
Nitro-Power! An exceptionally general electrophilicamination of zinc organyl compounds was developed, and yields alkylated aromatic aminoboranes from commercially available nitroarenes. The partially reduced nitro group is directly engaged as an electrophilic nitrogen intermediate. The aminoboranes were reacted with electrophiles, thereby incorporating two different substituents at the N atom of the
Straighforward access to various saturated amines from allylic alcohols and isostructural mixture can now be achieved in the presence of arene ruthenium catalyst featuring phosphinesulfonate ligand and a hydrogen donor.
The use of tertiaryamines as surrogates for secondary amines has prominent advantages in terms of stabilization and ease of handling. A Ni-catalyzed transamidation of N-acylsaccharins with tertiary aromatic amines is reported. By using tert-butyl hydroperoxide as the terminal oxidant, this reaction permits selective cleavage of the C(sp3)–N bonds of unsymmetrical tertiary aromatic amines depending
使用叔胺作为仲胺的替代品在稳定性和易于处理方面具有突出的优势。报道了 N-酰基糖精与叔芳香胺的 Ni 催化转酰胺作用。通过使用叔丁基过氧化氢作为末端氧化剂,该反应允许根据烷基取代基的大小选择性裂解不对称叔芳胺的 C(sp3)-N 键。
