Anionic Bismuth(III) chloride cluster with diselenide countercations: Application in C-S cross coupling reactions

Dinuclear complexes, a one dimensional chain and a two dimensional layer of bismuth(iii) chalcogenones for C–S cross coupling reactions

“…Thus, catalyst 3 exhibited a better catalytic activity in terms of the catalyst loading, reaction time, and temperature. Based on previous reports, 21–23 we presume that the reported catalytic conversion may occur through Lewis-acid-type catalytic reactions.…”

“…22 Later, we reported a semi-super-bulky anionic bismuth( iii ) chloride cluster for C–S coupling reactions. 23 However, the catalytic applications of bismuth( iii ) coordination polymers have never been investigated. Thus, complexes 1–4 are used as catalysts for C–S bond-forming reactions with aryl thiophenols and heteroaryl halides under aerobic conditions.…”

“…Catalyst 3 is more active at a lower temperature compared to a bismuth( iii ) cluster-based catalyst. 23 Similarly, catalyst 3 is better than copper oxide (at 110 °C), 25 palladium phosphine (at 115 °C), 26 or nickel carbene (at 100 °C) 27 catalysed heteroarylation of arene thiols at high temperatures under an inert atmosphere. Thus, catalyst 3 exhibited a better catalytic activity in terms of the catalyst loading, reaction time, and temperature.…”

N‐Heterocyclic Thione‐Coordinated Dinuclear Bismuth(III) Trihalides with a Rare Geometry

“…Thus, a wide range of metal derivatives was synthesized and investigated for various catalytic applications [6–15] . The chemistry of NHE ligands with p ‐block elements, particularly Sb and Bi, has been studied in detail [16–20] . The mesoionic chalcogenone (MIE) and its metal derivatives are few in comparison to traditional NHE ligands [21,22,23] .…”

Antimony(III) Halide‐Assisted Stereospecific Coordination of Thione

“…Since then, interest in NHCs and their analogs, such as cyclic urea derivatives of N‐heterocyclic chalcogenones ligands, (NHCh) (Ch=O, S, Se, and Te) have shown their ability to act as robust σ‐donor ligands [8] . Several main group NHCh complexes have been proven to be especially beneficial in many homogeneous catalytic reactions [9–11] . Although the structure of several main group NHCh complexes have been reported with unique bonding and rich structural diversity, antimony NHCh complexes remains rare in the literature.…”
