Synthesis and crystal structure of triphenyltin and lead complexes with organic peroxides

Non-covalent interactions of the hydroperoxo group in crystalline adducts of organic hydroperoxides and their potassium salts

“…It was recently shown that organic hydroperoxides act as ligands towards main group elements and form the corresponding coordination peroxo compounds after deprotonation with base. 29 In this regard, new systems that contain either deprotonated hydroperoxides or both hydroperoxides and a base seem to be convenient and demandable reagents for the outlined coordination chemistry. This sets the search for coformer candidates as an important step in the process of chemical synthesis and characterization of new HPCA.…”

Organoantimony Dihydroperoxides: Synthesis, Crystal Structures, and Hydrogen Bonding Networks

“…H 2 O 2 is known to be a weak ligand; 46−50 hence, hydroperoxo and peroxo complexes can be formed after deprotonation of H 2 O 2 or organic hydroperoxide in the presence of a base. 46,50,51 Another prerequisite for the formation of hydroperoxo complexes is the use of a large excess of concentrated H 2 O 2 , which prevents the formation of peroxo-bridged complexes. 24,29 in the THF/Et 2 O reaction system in the presence of gaseous dry ammonia, followed by the concentration of the reaction system and addition of an excess of THF, Et 2 O, MeOH, or desiccant agent Na 2 SO 4 .…”

“…Organic peroxides (ROOH) are one class of non-radicals and are considered selective oxidizing agents widely applied in the oxidation process to obtain various molecules such as epoxides, ketones, and aldehydes. 131 Another non-radical species, CO, as a ubiquitous inorganic gas, is mainly produced by heme oxygenase (HO) in vivo. 132 CO regulates metabolism by combining with reducing transition metals, for example by activating guanine cyclase (GC) to generate guanosine 3,5-cyclic monophosphate (cGMP) to further regulate vasodilation and nerve transmission.…”
