Abstract Halogen(I) complexes are widely used as halogenation reagents and traditionally feature homoleptic stabilising Lewis bases, though the recent revitalisation of iodine(I) carboxylate chemistry has provided isolable examples heteroleptic complexes. This work reports pnictogenate stabilised by a base (L), Ph 2 P(O)O─I─L, synthesised via cation exchange from silver(I) precursor, (Ph P(O)OAg) n . The were characterised in both solution ( 1 H, H- 15 N HMBC, 31 P) solid state, supplemented computationally DFT studies. Interestingly, these pnictogenates demonstrate range stabilities, have been found to excel iodination comparison carbonyl hypoiodites, with comparable reactivity eponymous Barluenga’s reagent antipyrine.

Traditional chemical processes often generate substantial waste, leading to significant pollution of water, air, and soil. Developing eco-friendly methods is crucial for economic environmental sustainability. Mechano-driven chemistry, with its potential material recyclability minimal byproducts, well-aligned green chemistry principles. Despite origins over 2000 years ago nearly 200 scientific investigation, mechano-driven has not been widely implemented in practice. This likely due a lack comprehensive understanding the complex physical effects mechanical forces, which challenge reaction efficiency scalability. review summarizes historical development discusses progress across various mechanisms, including mechanochemistry, tribochemistry, piezochemistry, contact electrification (CE) chemistry. CE-induced reactions, involving ion transfer, electron radical generation, are detailed, emphasizing dominant role radicals initiated by transfer influence through electrical double layer (EDL) formation. Advancing efficient, eco-friendly, controllable technologies can reduce reliance on traditional energy sources (such as electricity heat) toxic reagents, fostering innovation synthesis, catalytic technologies, establishing new paradigm broader applications.
