Herein, ionic liquid 1-ethyl-3-methylimidazolium dicyanamide and sodium tetraphenylborate were employed as joint precursors to facilely prepare micro-mesoporous core-shell carbon with sp. surface area up to 2870 m2 g-1, consisting of smooth unpenetrated shell and secondary hollow spherical carbon core. The as-obtained core-shell carbon as metal-free catalyst exhibited good performance for self-coupling and cross-coupling of amines RCH2NH2 (R = Ph, furan-2-yl, cyclohexyl, etc.), R1NH2 (R1 = Ph, n-hexyl, cyclohexyl, etc.) to achieve the corresponding symmetry RCH=NCH2R and asymmetry imines RCH=NR1 under mild and neat conditions. Excitingly, for the challenging aliphatic amine cyclohexylmethanamine, the desired imines RCH=NCH2R (R = cyclohexyl) were achieved in 55.9% yield. The nearly linearly correlation between imine yield and ID/IG indicated that the resulting defects from departure of heteroatoms during pyrolysis may be active site.
