Grapefruit pulp is reacted with an alcohol or ketone, preferably a polyhydric alcohol such as propylene glycol or glycerin, in the presence of a free radical initiator such as ultraviolet light to produce a stable reaction product useful as an ingredient in various cosmetic products and for ...
Nitriles(RCN) react withGrignard reagentsto produce ketones, followinghydrolysis(RCN + R′MgX → RCOR′). Ketones possessing α-hydrogens can often be made to undergo aldol reactions (also calledaldol condensation) by the use of certain techniques. The reaction is often used to close rings, ...
These results indicate that the allylic alcohol reacted with the zero-valent nickel catalyst to generate a catalytic amount of OH−, which promoted keto–enol tautomerization. Fig. 6: Mechanism Study of the Allylic Alkylation Reaction of Ketones. a Deuterium-labeling experiments. b Transition-...
chemicallyresistant material. The retention oftensile propertiesfor unreinforced PAEK resins is greater than 75%. Fiberglass reinforced PAEK resins exhibit a higher retention rate of tensile properties, but show some loss of tensilestrength properties. Unreinforced PAEK resins react chemically with acids ...
Allylsilacycles bearing a chiral 1,2-diol, β-aminoalcohol, or 1,2-diamine ligand have been utilized for enantioselective allylation of aldehydes.102,102a,103,106,106aAs mentioned above, they react with aldehydes spontaneously. Among them, allylsilacycles16show the highestenantioselectivity(Equation...

Ketones react reversibly with methanol, in hydrogen chloride solution, to form hemiketals, the extent of reaction depending on the steric size and proximity of neighboring groups. The order of ease of formation (percentage of ketone reacting) is unhindered sixmembered ring ketone (90) > ...
(1) Under the presence of an inertic solvent and sodium solid alcohol that reacts, the γ-butyl dectind compounds selected from the type (Ⅰ) occur in the molecular dehydration and contraction, and the intermediate of the general (II); ...
