Chemoselective Hydrogenation of Nitroarenes Catalyzed by Molybdenum Sulphide Clusters
Wiley (2017-03-20)Herein, we describe an atom efficient and general protocol for the chemoselective hydrogenation of nitroarenes to anilines catalyzed by well-defined diimino and diamino cubane-type Mo3S4 clusters. The novel diimino ... -
Chemoselective Transfer Hydrogenation to Nitroarenes Mediated by Cubane-Type Mo3S4 Cluster Catalysts
Wiley (2012-07)Chemoselective cubes: Cubane-type [Mo3S4X 3(dmpe)3]+ clusters (dmpe=1,2-(bis) dimethylphosphinoethane), in combination with an azeotropic 5:2 mixture of HCOOH and NEt3 as the reducing agent, act as selective cluster catalysts ...

Efficient (Z)-selective semihydrogenation of alkynes catalyzed by air-stable imidazolyl amino molybdenum cluster sulfides
Royal Society of Chemistry (2023-02-16)Imidazolyl amino cuboidal Mo3(μ3-S)(μ-S)3 clusters have been investigated as catalysts for the semihydrogenation of alkynes. For that purpose, three new air-stable cluster salts [Mo3S4Cl3(ImNH2)3]BF4 ([1]BF4), [Mo3S4Cl3( ... -
Efficient and Selective N‐Methylation of Nitroarenes under Mild Reaction Conditions
Wiley (2017)Herein, we report a straightforward protocol for the preparation of N,N‐dimethylated amines from readily available nitro starting materials using formic acid as a renewable C1 source and silanes as reducing agents. This ...

General and selective iron-catalyzed transfer hydrogenation of nitroarenes without base
American Chemical Society (2011-08)The first well-defined iron-based catalyst system for the reduction of nitroarenes to anilines has been developed applying formic acid as reducing agent. A broad range of substrates including other reducible functional ...

Selective Dehydrogenation of Formic Acid Catalyzed by Air-Stable Cuboidal PN Molybdenum Sulfide Clusters
Wiley (2023-09-13)Formic acid is considered as a promising hydrogen storage material in the context of a green hydrogen economy. In this work, we present a series of aminophosphino and imidazolylamino Mo3S4 cuboidal clusters which are active ...

Selective reductive amination of aldehydes from nitro compounds catalyzed by molybdenum sulfide clusters
Royal Society of Chemistry (2017-07)Secondary amines are selectively obtained from low value starting materials using hydrogen and a non-noble metal-based catalyst. The reductive amination of aldehydes from nitroarenes or nitroalkanes is efficiently catalyzed ...

Unprecedented Mo3S4 cluster-catalyzed radical C-C cross-coupling reactions of aryl alkynes and acrylates
Royal Society of Chemistry (2024-01-30)A new method for the generation of benzyl radicals from terminal aromatic alkynes has been developed, which allows the direct cross coupling with acrylate derivatives. Our additive-free protocol employs air-stable diamino ...
