Abstract

In this study, a strongly feasible method for the reduction of nitrobenzene has been developed through highly stable and thermally robust iron chalcogenide carbonyl clusters Fe3E2(CO)9 (E = S, Se or Te).

Iron- and copper-based bifunctional catalysts for the base- and solvent-free C–N coupling of amines and aryl/benzyl chlorides under aerobic conditions

“…S1–S9, ESI†). Based on these fundamental characterizations and the evidences available in the literature, 31 a plausible mechanism is proposed (ESI,† Scheme S12). We believe there might be the formation of an adduct ( 4 ) by the interaction of the Fe(0) cluster and Cu(OAc) 2 , which may be the active catalytic species for the reaction.…”

“…Fe(CO) 5 , Fe 2 (CO) 9 and Fe 3 (CO) 12 are the most common ZVI complexes having significant catalytic potential. [22][23][24][25][26][27][28][29][30][31] Here, we wish to report the Fe 3 Se 2 (CO) 9 cluster in combination with Cu(OAc) 2 as an excellent catalyst for the C-N coupling reaction (Scheme 1). This bimetallic catalytic methodology is highly economical, and works under aerobic conditions.…”

Half‐Sandwich (η6‐Benzene)Ruthenium(II) Complex of Picolyl Functionalized N‐Heterocyclic Carbene as an Efficient Catalyst for Thioether Directed C−H Alkenylation of Arenes

“…Nevertheless, it is worthy to use thioether as a directing group, as under reductive conditions these groups can be easily removed. [14] Furthermore, thioether could go through a variety of useful transformations, [15][16][17] sulphur is also found in various useful molecules including functional material, organocatalyst [18][19][20][21] and water reduction catalyst. [22][23] Zhang and co-workers reported a Pd catalyzed CÀ H bond alkenylation of thioethers in 2012 (Scheme 1).…”
