PURPOSE:3-Amino- or substituted-amino-2-cycloalkenones are made to react with water or an alcohol to effect hydrolysis or alcoholysis, thereby readily producing title compound, an intermediate of medicines, agricultural chemicals, perfumes, stabilizers for synthetic resins. CONSTITUTION:3-Amino-2-...
The reactions of alkane molecular ions (RH2+) with water vapor were found to proceed via a bimolecular mechanism in both ethane and propane. Parent ions from cyclohexane, cyclopentane,i‐butane,n‐butane,i‐pentane,n‐pentane, andn‐hexane were observed to react exclusively via a termolecular ...
Haloalkanes can undergo hydrolysis and give alcohol and halide ion as products.HaloalkaneNucleophile(a)與水(OH)反應React with Water(OH)1,一級及二級鹵烷只能與水有輕微反應The reaction with the primary and secondar 5、y haloalkanes are less reactive由於水分子的氧原子帶有微弱負電荷()及兩對孤偶...
When provided sufficient activation energy, alkanes react with oxygen to produce carbon dioxide, water, and energy, thus alkanes are valuable fuels. The process of cracking breaks longer chains alkanes into smaller alkanes and alkenes to increaseoctane numberand to make polymers. C4-C6alkanes may be...
Grignard reagents react rapidly with acidic hydrogen atoms in molecules such as alcohols and water. When a Grignard reagent reacts with water, a proton replaces the halogen, and the product is an alkane. The Grignard reagent therefore provides a pathway for converting a haloalkane to an alkane...
superior in energy efficiency and alkene conversion, and capable of manufacturing a high branching isoalkane in a good yield by bringing a plurality of specified compounds into contact with a silicon oxide or the like, also bringing water and water vapor into contact with them and then burning ...
This generally refers to alkanes lower than n-butane. Because thecarbon chainsare too short, methane and ethane cannot be subjected to secondary oxidation and chain branching reactions. The only method is to directly decompose them into OH or HO2through peroxy and react with HO2to generate H2O2...

Benzophenone reacts with (55) and the stability of the dianion (56), greater than that of the corresponding monoanion, suppresses the reversibility of the addition process. Clean reactions and satisfactory yields depend on careful control of the temperature of these reactions at −90 °C. Under...
