Exempel på hur man kan använda ALKOXIDES i en mening

• Metal oxides, hydroxides, and especially alkoxides are basic, and conjugate bases of weak acids are weak bases.
• Gilman concentrated on preparing volatile uranium derivatives, mainly dealing with alkoxides, and the syntheses of species with potential anti-malarial activities.
• As indicated by their formula, these alkoxides can adopt complex structures ranging from monomers to tetramers.
• Many metal alkoxides contain methoxy groups, such as tetramethyl orthosilicate and titanium methoxide.
• Organometallic superbases, sometimes called Lochmann–Schlosser superbases, result from the combination of alkali metal alkoxides and organolithium reagents.
• The order of reactivity of alkoxides, K > Na >> Mg, is consistent with higher electron density on oxygen, hence increasing the alkoxide nucleophilicity.
• Another way to evaluate the content of peracids and peroxides is the volumetric titration with alkoxides such as sodium ethoxide.
• Derivatives of noted interest include the hexalkoxyphosphazene lubricants obtained from nucleophilic substitution of hexachlorophosphazene with alkoxides, or chemically resistant inorganic polymers with desirable thermal and mechanical properties known as polyphosphazenes produced from the polymerisation of hexachlorophosphazene.
• Metal β-diketonates, metal alkoxides, metal dialkylamides, transition metal carboxylate complexes, metal acetylacetonates, and metal phosphine complexes are representative members of this class.
• The Kulinkovich reaction describes the organic synthesis of substituted cyclopropanols through reaction of esters with dialkyl­dialkoxy­titanium reagents, which are generated in situ from Grignard reagents containing a hydrogen in beta-position and titanium(IV) alkoxides such as titanium isopropoxide.
• Subsequently, these trialkyl compounds are oxidized to aluminium alkoxides, which are then hydrolysed:.
• In the usual circumstance, surface MOH groups react as nucleophiles with silyl chlorides or silyl alkoxides.
• Alternatively, dehydrohalogenation of chlorodifluoromethane or bromodifluoromethane using alkoxides or alkyllithium also produces difluorocarbene:.
• Like other alkali metal alkoxides, lithium methoxide adopts a polymeric structure Its solubility in common polar aprotic solvents like THF is low; however, it is soluble in methanol and is available commercially as a 10% solution.
• It is a good electrophile, and the sulfimide S=N bond can be attacked by nucleophiles, such as alkoxides, enolates, and amide ions.
• LF-FSP, as invented at the University of Michigan, uses metalloorganic precursors such as metal carboxylates or alkoxides, not metal chlorides.
• PFCAs have shown reactivity with a wide variety of nucleophiles including phenoxides, alkoxides, organometallic, amines, thiols, and azoles.
• His work covered the synthesis of several metallic compounds such as polymetaphosphates, alkoxides, beta-diketonates, carboxylates, thiolates and dialky 1 dithiophosphates.
• p-Dioxanone can undergo ring-opening polymerization catalyzed by organic compounds of tin, such as tin(II) octoate or dibutyltin dilaurate, or by basic alkoxides such as aluminium isopropoxide.
• These chloride groups are susceptible to displacement by amines and alkoxides, giving rise, ultimately, to a large family of naphthalimides, which are used as optical brighteners.
