Organophosphorus chemistry is a broad and exciting field, with potential opportunities for researchers involved in multi-disciplinary areas of scientific endeavour, including organic, medicinal, pharmaceutical, agricultural, industrial chemistry. compounds find extensive applications all these fields owing to their inherent physical biological properties. Since its first development the 90s, green sustainable has grown considerably over past two decades. It become much more prevalent among working branches chemical science. As part noteworthy developments, synthetic organic chemists have been motivated develop eco-friendly methodologies generating phosphorus-functionalised interest, focusing on various principles. result, considerable progress towards accomplished during last decade. In continuation our earlier contributions, this chapter also aims offer an overview such developments approaches organophosphorus reported 2021.

Primary vinylarenes are important monomers for the production of materials, which in our case ion exchange membranes electrolyzers. Given high cost certain but relative affordability their aldehyde precursors, we explored synthesis using flow chemistry to enable facile and safe scale-up. While a soluble, methanolic Wittig reaction found limited success, an alternative approach involving Peterson olefination was high-yielding. This required (trimethylsilyl)methyl Grignard reagent, generated magnesium-filled column. Thus, 2-vinylthiophene obtained 93% yield at 37 g scale, route applicable other nonpolar arenes. For polar arenes, precipitation oxymagnesium chloride stage inefficient elimination were observed, these challenges could be mitigated by employing (phenyldimethylsilyl)methyl reagent instead stronger acid higher temperature elimination.

Organophosphorus compounds (OPC) are a large class of organic that provide wide range applications, and their importance has grown steadily in recent years. In each category family, these have similarities differences. Due to immense variety, chemicals various properties and, therefore, applications. fact, works been published recently present the main applications OPC, especially metal extraction. Despite extemsive use, optimizing performance as extractant agents remains challenge due structural variability sensitivity process parameters. This review provides critical analysis pentavalent OPCs, focusing on how chemical nature influences heavy extraction efficiency. For first time, we novel classification system for OPCs based phosphorus valency heteroatom coordination, offering framework guide future research. Our findings reveal direct coordination heteroatoms such oxygen, sulfur, nitrogen great influence physicochemical characteristics observation is line with Pearson’s Hard Soft Acids Bases (HSAB) theory sense it demonstrates altering alters affinity ligand. As result, modifications can improve by up 40% some metals, highlighting potential optimized molecular designs maximize industrial future, this work offers solid foundation studies rational design organophosphorus-based extractants. Using HSAB our system, researchers rationally target unparalleled precision. These results transformative impacts recovery efficiency-intensive sectors like mining, waste recycling, clean energy technologies.

Denton's redox-neutral catalytic Mitsunobu reaction is remarkable in that it translates a traditionally driven by the consumption of sacrificial chemical reagents to an additive-free manifold. Rational attempts improve system have been met with only marginal improvements, and lack consensus concerning rate-determining step continues limit effective development. Here, we analyze mechanism focusing on critical, largely overlooked element: removal water using Dean-Stark apparatus. Experimental analysis process, coupled extensive kinetic simulations, demonstrates overall rate intimately tied removal. This process can be viewed as transition between potential energy surfaces and, consequently, subsequent steps progress spontaneously absence water, allowing explanation how Le Chatelier's principle, thermodynamic effect, profound influence over reaction. We identify three bottlenecks inform catalyst design. Additionally, (a) clarify ongoing discussion regarding step, (b) provide clear advice future design taking into account role (c) discuss context formally endergonic esterification reactions, noting parallels ratchet mechanisms. Finally, highlight general principles catalyst/reaction emerge from our implement findings demonstrate 50% acceleration resulting improved removal, substantially greater enhancement than previously obtained computationally guided structural changes.

An asymmetric Michael addition of malononitrile to vinyl phosphonates was accomplished by hydrogen bond-enhanced bifunctional halogen bond (XB) catalysis. NMR titration experiments were used demonstrate that bonding, with the support hydrogen-bonding, played a key role in activation acceptors through phosphonate group. This is first example use XBs for organophosphorus compounds synthesis. In addition, iodo-perfluorophenyl group proved be better directing unit than different iodo- and nitro-substituted phenyl groups. The developed approach afforded products up excellent yields diastereoselectivities good enantioselectivities.
