[PDF] Reductions of Carboxylic Acids and Esters with NaBH4 in Diglyme …
Reductions of Carboxylic Acids and Esters with NaBH4 in Diglyme at 162°C. Abstract Aromatic esters, including the extremely sterically hindered ester: t-amyl 2-chlorobenzoate, are readily reduced to the corresponding benzyl alcohols in high yield with NaBH4 in refluxing diglyme (162°C). In sharp contrast, aliphatic esters usually gave only ...

18.7: Reduction of Carboxylic Acids and Their Derivatives
Reduction of Acid Chlorides and Esters. Acid chlorides can be converted to aldehydes using lithium tri-tert-butoxyaluminum hydride (LiAlH(Ot-Bu) 3).The hydride source (LiAlH(Ot-Bu) 3) is a weaker reducing agent than lithium aluminum hydride.Because acid chlorides are highly activated they still react with the hydride source; however, the formed aldehyde …

Electrochemically active species in aluminum
Electrochemically active species in aluminum (Al) electrodeposition baths using AlCl 3 and less volatile solvents i.e. glymes were investigated. Raman spectroscopy revealed that all the glyme baths contained AlCl 4 − anions and Al-Cl-glyme cations as ionic species. Room temperature conductivities were as high as the order of 10 −3 S cm −1 …

[PDF] A New Powerful Reducing Agent—Sodium
The addition of aluminum chloride to sodium borohydride in the dimethyl ether of diethylene glycol (diglyme) gives a clear solution with enormously more powerful reducing properties than those of sodium borohydride itself. Esters, lactones and carboxylic acids are readily reduced to the corresponding alcohols. Sodium salts of the carboxylic acids are …

A concentrated aluminum chloride (AlCl3)–diglyme (G2) electrolyte is used to prepare hard and corrosion-resistant aluminum (Al) electrodeposited films. The Al electrodeposits obtained from the electrolyte with an AlCl3/G2 molar ratio x = 0.4 showed a void-free microstructure composed of spherical particles, in stark contrast to flake-like …

tetrabutylammonium chloride (TBAC) additive in diglyme. This electrolyte does not comprise corrosive AlCl 3 as the main electrolyte salt; instead, we only use a small amount (0.1 M) of organic additive, TBAC, with Al(OTf) 3 as the main salt (0.5 M) dissolved in diglyme. The advantage of using TBAC is first seen in terms of high reversibility and
