well-defined hydride Mn(I) PNP pincer complex, recently developed in our laboratory, catalyzes this process in a very efficient way, and a total of 28 different aminomethylated products were synthesized and isolated yields of up to 91%. In a preliminary study, a related Fe(II) PNP pincer complex was shown to catalyze the methylation of 2-naphtol rather than its aminomethylation displaying again the divergent

New way to benzylic amines! Fe‐catalyzed oxidative cross‐coupling of electron‐rich heteroarenes and methylamines is established. Under the influence of FeCl2/bipy catalyst and oxidant (pyridine N‐oxide or H2O2), thiophenes, furans, indoles, and azaindoles cross‐couple with methylamines to furnish the corresponding benzylic amines. An intramolecular CH/CH coupling of a thiophene is observed to afford
苯甲基胺的新方法!建立了富电子杂芳烃和甲胺的铁催化氧化交叉偶联。在FeCl 2 /联吡啶催化剂和氧化剂(吡啶N-氧化物或H 2 O 2)的影响下,噻吩,呋喃,吲哚和氮杂吲哚与甲胺交联,得到相应的苄胺。分子内Ç H / C h的噻吩的偶联,观察到,得到良好的配体对σ 1受体蛋白。
