Abstract Herein, we report an inexpensive first‐row transition metal Ni heterogeneous catalytic system for the C sp 3 ‐mono alkylation of fluorene using alcohols as alkylating agents via borrowing hydrogen strategy. The protocol displayed versatility with high yields desired products various types primary alcohols, including aryl/hetero aryl methanols, and aliphatic agents. catalyst NPs@N−C was synthesized high‐temperature pyrolysis strategy, ZIF‐8 sacrificial template. characterized by XPS, HR‐TEM, HAADF‐STEM, XRD ICP‐MS. is stable even in air at room temperature, excellent activity could be recycled 5 times without appreciable loss its activity.
