Heterogeneously Ni–Pd nanoparticle-catalyzed base-free formal C–S bond metathesis of thiols

Abstract

This study rationally designed a heterogeneously catalyzed system (i.e., using Ni–Pd alloy nanoparticles supported on hydroxyapatite (Ni–Pd/HAP) under an H2 atmosphere) achieving an efficient base-free formal C–S bond metathesis of...

Carbon−Sulfur Coupling Reactions Catalyzed by Nickel(II) N‐Heterocyclic Carbene Complexes

“…1 H & 13 C NMR of coupling products are provided in Figures S21–S58. The authors have cited additional references within the Supporting Information [24a,b,31d,32b,c,37,42–43] …”

One-pot thiol-free synthetic approach to sulfides, and sulfoxides selectively

“…Next, we turned towards the preparation of bisbenzylthio systems. In this regard, several dibromides were successfully converted into bis(benzylthio) derivatives (19)(20)(21)(22)(23)(24) in good to excellent yields (Scheme 4). The single-crystal structures for 20a and 21b are presented in Fig.…”

“…2. 15 c ,22 It is observed from the literature that synthetic strategies for Csp 3 –S–Csp 3 type of sulfides/sulfoxides are much less explored as compared to Csp 2 –S–Csp 2 and Csp 2 –S–Csp 3 sulfides 23 /sulfoxides 24 despite having significant applications (Fig. 1).…”

A halogen bonding assembled hybrid copper halide framework as a promising hypotoxicity photodetector

“…However, aryl thioethers are tra-ditionally obtained from intricate multi-step organic syntheses, which involve complex organic reagents and inactive substrates, limiting the functionalization of aryl thioether and thereby hindering the achievement of photoconductive HCHs (Scheme S1 †). 33 Although recently copper has been explored as a catalyst to boost the synthesis of aryl thioethers, 34,35 it still has several limitations with regards to synthesizing HCHs: (i) the reactions still need harsh reaction conditions, e.g., UV light or strong base, (ii) toxic aryl halides were indispensable 36 and (iii) the derived aryl thioether must participate in additional coordination reactions to form HCHs.…”
