The acetone is coordinated to the aluminium which activates it for the hydride transfer from the alkoxide. The aluminium-catalyzed hydride shift from the α-carbon of the alcohol to the carbonyl carbon of acetone proceeds over a six-membered transition state (8). The desired ketone (9) is formed after the hydride transfer. [4]
The Bouveault–Blanc reduction, employing a mixture of sodium metal in the presence of alcohols, was an early method for reduction of carbonyls. [32] It is now largely obsolete. Subsequent to the discovery of the Bouveault–Blanc reduction, many methods were developed, including the major breakthrough of catalytic hydrogenation where H 2 ...
Wine packaged in a bag usually made of flexible plastic and protected by a box, usually made of cardboard. The bag is sealed by a simple plastic tap. Brettanomyces A wine spoilage yeast that produces taints in wine commonly described as barnyard or band-aids. Brix/Balling A measurement of the dissolved sucrose level in a wine Brouillis
Through a variety of mechanisms, the removal of a hydride equivalent converts a primary or secondary alcohol to an aldehyde or ketone, respectively. The oxidation of primary alcohols to carboxylic acids normally proceeds via the corresponding aldehyde, which is transformed via an aldehyde hydrate (gem-diol, R-CH(OH) 2) by reaction with water ...
Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds.

acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
