Mechanism of Important Name Reactions Aldol Condensation: We can define aldol condensation as an organic reaction in which an enolate ion reacts with a carbonyl compound to form β-hydroxy aldehyde or β-hydroxy ketone, followed by dehydration to give a conjugated enone. Balz-Schiemann Reaction: ...

Synthesis and some reactions of 3,5-di-O-methyl-d-glucose and -fructose Hydrolysis of 1,2-O-isopropylidene-3,5-di-O-methyl-伪-d-glucofuranose by strong acid yielded 3,5-di-O-methyl-d-glucofuranose (6) and its 1,6-anhydride (10). The mechanism of the reaction giving 10 is discu...
thesis, named reactions form a useful and very special vocabulary, as the name immediately conveys information about the type of reaction, the starting materials, the conditions required, and the mechanism. In such a complex field as organic synthesis, a vocabulary with so concentrated an informatio...

aWith Portland cement at ordinary temperature, the strength increases detectably over at least two tears. The reactions that cause setting and hardening are collectively described as hydration reactions, though the use of the word is very loose, as the processes are usually more complicated than th...
Named Reactions Protecting Groups Simmons-Smith Reaction The Simmons-Smith reaction is the cyclopropanation of alkenes using a mixture of diiodomethane and zinc-copper couple. In modern variations, the zinc-copper couple is often replaced with diethylzinc. The reaction was first reported by Howard ...
