摘要: Abstract The reaction of arylimines with [RuCl2(p-cymene)]2 and 4 equiv. KOAc at room temperature in methanol leads to the formation N–Ru–C cycloruthenates RuCl(arylimine-kC,N)(p-cymene) 3a-3d via ortho C–H activation/deprotonation by acetate. presence stable Ru–Cl bond rather than a labile Ru–OAc is crucial for isolation complexes. This preparative method cyclometallates was applied 2-phenyloxazoline, benzo[h]quinoline improved synthesis 2-phenylpyridine 1-phenylpyrazole derivatives. molecular structures three are reported.
