Fe SAC on Nitrogen-Doped Carbon: An Efficient Catalyst for S-Alkylation of Dithiocarbamates via Borrowing Hydrogen Strategy

Herein we report, the synthesis of single-atom iron on nitrogen-doped carbon as a catalyst for the direct formation of Csp3-S bond via borrowing hydrogen strategy using alcohols as the alkylating agent. The catalyst was synthesized by encapsulating ferrocene within the ZIF-8 framework, followed by pyrolysis and characterized precisely by FE-SEM, HR-TEM, XPS, Raman, XRD and EXAFS. The catalyst is robust, displayed an excellent reactivity in borrowing hydrogen reaction and could be recycled five times without any appreciable loss in activity. Fe single atom on nitrogen doped carbon as efficient, bench stable and recyclable catalyst for S-benzyl/alkylation of dithiocarbamates via borrowing hydrogen strategy. A wide range of functional groups are well tolerated and gave the desired dithiocarbamate products in good to excellent yields. image
