A selective C(3)-alkylation via activation/functionalization of sp(3) C-H bond of saturated cyclic amines was promoted by (arene)ruthenium(II) complexes featuring a bidentate phosphino-sulfonate ligand upon reaction with aldehydes. This highly regioselective sustainable transformation takes place via initial dehydrogenation of cyclic amines and hydrogen autotransfer processes.
(芳烃)钌(II)配合物通过与醛反应具有二齿膦基磺酸盐配体促进了通过饱和环胺的sp(3)CH键的活化/官能化的选择性C(3)-烷基化。这种高度区域选择性的可持续转化是通过环胺的初始脱氢和氢自动转移过程发生的。
