CHEM-GUIDE: Chemical properties of alkene

Addition reactions The p electrons of the carbon-carbon-double bond are available to an electrophile (any species seeking electrons). Thus, the addition reactions shown by alkenes are in fact electrophilic addition reactions. addition product Some addition

Alkene Additions: Regiochemistry

"In the addition of HX to an alkene, the acidic hydrogen becomes attached to the carbon with fewer alkyl substituents, and the X group becomes attached to the carbon with more alkyl substituents." Another way of saying this is that "the hydrogen-rich atom becomes hydrogen-richer", i.e., the hydrogen of HX gets attached to the carbon that had more hydrogens in the first place.

Ch17: Nucleophilic Addition

Nucleophilic Addition Nucleophilic addition reactions are an important class of reactions that allow the interconversion of C=O into a range of important functional groups. What does the term "nucleophilic addition" imply ?A nucleophile, Nu-, is an electron rich species that will react with an electron poor species (here the C=O)

Benzene Reactions | Halogenation, Nitration and …

Due to its high degree of unsaturation, it is highly reactive. Unlike alkenes, it never participates in addition, oxidation, and reduction reactions. For example, benzene won''t react with Br, HCl or other reagents to result in carbon-carbon double bonds formation.

How carbon-containing nucleophiles attack aldehydes and ketones to form alcohols. Voiceover: We''ve seen a lot of nucleophilic addition reactions to aldehydes and ketones and in this video we''re going to look at the addition of carbon nucleophiles.

Conjugated nitrosoalkenes as Michael acceptors in …

Addition of C–H acids anions to conjugated nitrosoalkenes Stabilized enolates and their equivalents are the most studied C-nucleophiles in Michael addition reactions with nitrosoalkenes. A first systematic study in this area was done by Ohno and co-authors , who reported the addition of diethyl malonate and acetylacetone anions to cyclic nitrosoalkenes NSA1a–c generated from the

New Electroalyst Turns Carbon Dioxide Into Liquid Fuel

2020/8/9· New electroalyst efficiently converts carbon dioxide into ethanol. alysts speed up chemical reactions and form the backbone of many industrial processes. For example, they are essential in transforming heavy oil into gasoline or jet fuel. Today, alysts are involved in over 80 percent of all

Nucleophilic Addition Reactions - Aldehydes and …

6.2 Nucleophilic Addition Reactions In each of the following reactions, the general reaction mechanism is the same: nucleophilic addition to a carbonyl. This is one of the most important reaction mechanisms on the M, and many of the reactions of aldehydes, ketones, and more complex molecules share this general reaction mechanism.

Carbonyl Compounds: Nomenclature, Nucleophilic …

2020/3/23· Reactions of aldehydes and ketones are limited to nucleophilic addition reactions only. The attack of the nucleophile is through the electrophilic carbon atom of the target molecule. The electrophilic carbon atom becomes somewhat electron-deficient due to the pull of electrons toward the oxygen atoms.

Isocyanate Reactions

Isocyanate reactions are very susceptible to alysis that is alysts greatly increase the rate of nucleophilic addition of compounds with active hydrogen to the C=N bond. Widely used alysts include tertiary amines, such as triethylene diamine (TEDA), dimethylpiperazine (DMP), dimethylethanolamine (DMEA), and diazabicyclooctane (DABCO), as well as tin compounds like dibutyltin dilaurate
