Salt Metathesis: An Ultimate Click Reaction [PDF]
Precision ChemistryIn this Comment, we suggest salt metathesis (or ion exchange) as an ultimate click reaction, extending click chemistry principles beyond covalent bonds to ionic interactions. These universal and robust reactions, which nature utilizes in marine organisms' biomineralization processes, proceed spontaneously under mild conditions with minimal waste ...

European Journal of Inorganic Chemistry, 2023 AbstractConversions of organoelement diamides, ArDippE(NMe2)2 (E=Sb, Bi; ArDipp=C6H3‐2,6‐Dipp2), with Ph2SnH2 as reducing agent gave access to low‐valent, heavier group 15 dimers ArDippSb=SbArDipp and ArDippBi=BiArDipp, while only readily removable byproducts (i. e. dihydrogen, amines) and cyclo‐(Ph12Sn6) are generated during the reaction.

Organic Synthesis Based on Ruthenium Carbene Catalyzed Metathesis Reactions and Pyridinium Salt Photochemistry [PDF]
Journal of the Korean Chemical Society, 2010 ABSTRACT. In this account, three synthetic methodologies that serve as the basis for new strategies for the preparation of selected natural products are briefly introduced. One process, involving ruthenium carbene catalyzed ring rearrangement meta-thesis developed by Grubbs and his coworkers, transforms alkene-tethered cycloalkenes to thermodynamically

Obtaining salts of resin acids from Cuban pine by metathesis reactions
Biointerface Research in Applied Chemistry, 2020 The resin acids obtained from the Cuban pine rosin are the starting material for the development and application of metathesis reactions. These reactions allow the obtaining of salts with high added value which could be used in the development of biomaterials for dental use. The objective of this work was to obtain calcium, magnesium and zinc resinates

Characterization and Dynamics of Substituted Ruthenacyclobutanes Relevant to the Olefin Cross-Metathesis Reaction [PDF]
, 2011 The reaction of the phosphonium alkylidene [(H_(2)IMes)RuCl2═CHP(Cy)_3)]^(+) BF_(4)^− with propene, 1-butene, and 1-hexene at −45 °C affords various substituted, metathesis-active ruthenacycles. These metallacycles were found to equilibrate over extended
