C-Se cross-coupling of arylboronic acids and diphenyldiselenides over non precious transition metal (Fe, Cu and Ni) complexes

Understanding flow chemistry for the production of active pharmaceutical ingredients

“…The leaching in case of supported catalysis can be arrested by improving metal support interaction with deliberately developed surface defects ( Burange et al., 2016 ) and among others ( Burange et al., 2021 ). Coupling reactions over non-precious metals complexes are also reported in order to reduce the cost of the final catalyst ( Sahani et al., 2018a , 2018b , 2019 ). However, such homogeneous catalysts are difficult to recycle; therefore, there are few attempts on immobilization of them onto solid support ( Collis and Horváth, 2011 ).…”

Recent Advances in the Schiff Bases and N‐Heterocyclic Carbenes as Ligands in the Cross‐Coupling Reactions: A Comprehensive Review

“…Sahani et al [103] reported the synthesis of Cu, Ni, and Fe complexes with various tetradentate and tridentate ligands such as bishydrazone, salophane, bisbenzimidazolyl pyridine, and isonicotinohydrazide (C91-C95) as shown in Fig. 8.…”

“…In 2014, Kankala and co-workers [140] reported a facile synthesis of piperidine alkene-alkaloids including natural Patil et al [141] reported a series of substituted triazene dyes (103) prepared by coupling functionalized imidazol-2-ylidenes (L88 or L89) with various azides (vinyl, alkyl, aryl, and heteroaryl) (102) using NHCs generated in situ under alkaline conditions from the respective imidazolium salts in 49-97% yields as shown in Scheme 100.…”

Cross‐Coupling Reactions of Aryltriethoxysilanes and Diaryldiselenides ‐ A New Route for the Synthesis of Diarylselenides

“…The methods used to prepare organoselenium compounds can be broadly classified in two main categories: those that use (i) electrophilic organoselenium and (ii) nucleophilic organoselenium species. Synthetic routes for diarylselenides (see Figure ), involve coupling reactions of diphenyldiselnides with aryl halide over copper ferrite NPs, triarylybismuthane with elemental Se over Cu catalyst, arylselenols with arenediazonium salts, triarylbismuthane with diaryldiselenides in presence of light, PhSeSnBu 3 with aryl and alkyl halide in ILs, PhSeBr with organoboranes, organostannanes, and organosilane over alumina supported copper catalyst, aryl selenocyanate with boronic acids and silane over Cu‐Ag catalyst (decyanative approach), Ar‐Se‐Cl with boronic acids in ILs, diphenyldiselenides with boronic acids and coupling of Bu 3 SnSePh with aryl iodide and triflate over Pd catalysts …”
