Acetyl group

In organic chemistry, acetyl is a functional group with the chemical formula and the structure.

Adolf von Baeyer

Johann Friedrich Wilhelm Adolf von Baeyer (31 October 1835 – 20 August 1917) was a German chemist who synthesised indigo and developed a nomenclature for cyclic compounds (that was subsequently extended and adopted as part of the IUPAC organic nomenclature).

Alcohol (chemistry)

In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl functional group bound to carbon.

See Koenigs–Knorr reaction and Alcohol (chemistry)

Benzoyl group

In organic chemistry, benzoyl is the functional group with the formula and structure.

See Koenigs–Knorr reaction and Benzoyl group

Benzyl group

In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure.

Chemische Berichte

Chemische Berichte (usually abbreviated as Ber. or Chem. Ber.) was a German-language scientific journal of all disciplines of chemistry founded in 1868.

Emil Fischer

Hermann Emil Louis Fischer (9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. Koenigs–Knorr reaction and Emil Fischer are carbohydrate chemistry.

See Koenigs–Knorr reaction and Emil Fischer

Ester

In chemistry, an ester is a functional group derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group of that acid is replaced by an organyl group.

See Koenigs–Knorr reaction and Ester

Ether

In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom bonded to two organyl groups (e.g., alkyl or aryl).

See Koenigs–Knorr reaction and Ether

Fischer glycosidation

Fischer glycosidation (or Fischer glycosylation) refers to the formation of a glycoside by the reaction of an aldose or ketose with an alcohol in the presence of an acid catalyst. Koenigs–Knorr reaction and Fischer glycosidation are carbohydrate chemistry, Name reactions and substitution reactions.

See Koenigs–Knorr reaction and Fischer glycosidation

Glycoside

In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Koenigs–Knorr reaction and glycoside are carbohydrate chemistry.

See Koenigs–Knorr reaction and Glycoside

Glycosyl

In organic chemistry, a glycosyl group is a univalent free radical or substituent structure obtained by removing the hydroxyl group from the hemiacetal group found in the cyclic form of a monosaccharide and, by extension, of a lower oligosaccharide.

See Koenigs–Knorr reaction and Glycosyl

Glycosyl donor

A glycosyl donor is a carbohydrate mono- or oligosaccharide that will react with a suitable glycosyl acceptor to form a new glycosidic bond. Koenigs–Knorr reaction and glycosyl donor are carbohydrate chemistry.

See Koenigs–Knorr reaction and Glycosyl donor

Halide

In chemistry, a halide (rarely halogenide) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically tennesside compound.

Helferich method

The Helferich method may refer to.

Intramolecular aglycon delivery

Intramolecular aglycon delivery is a synthetic strategy for the construction of glycans. Koenigs–Knorr reaction and Intramolecular aglycon delivery are carbohydrate chemistry.

Mercury(II) bromide

Mercury(II) bromide or mercuric bromide is an inorganic compound with the formula HgBr2.

See Koenigs–Knorr reaction and Mercury(II) bromide

Mercury(II) cyanide

Mercury(II) cyanide, also known as mercuric cyanide, is a poisonous compound of mercury and cyanide.

See Koenigs–Knorr reaction and Mercury(II) cyanide

Mercury(II) oxide

Mercury(II) oxide, also called mercuric oxide or simply mercury oxide, is the inorganic compound with the formula HgO.

See Koenigs–Knorr reaction and Mercury(II) oxide

Methyl group

In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula (whereas normal methane has the formula). In formulas, the group is often abbreviated as Me.

See Koenigs–Knorr reaction and Methyl group

Neighbouring group participation

In organic chemistry, neighbouring group participation (NGP, also known as anchimeric assistance) has been defined by the International Union of Pure and Applied Chemistry (IUPAC) as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma or pi bond contained within the parent molecule but not conjugated with the reaction centre.

See Koenigs–Knorr reaction and Neighbouring group participation

Nucleophilic substitution

In chemistry, a nucleophilic substitution (SN) is a class of chemical reactions in which an electron-rich chemical species (known as a nucleophile) replaces a functional group within another electron-deficient molecule (known as the electrophile).

See Koenigs–Knorr reaction and Nucleophilic substitution

Organic chemistry

Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

See Koenigs–Knorr reaction and Organic chemistry

Pindone

Pindone is an anticoagulant drug for agricultural use.

See Koenigs–Knorr reaction and Pindone

Reaction mechanism

In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs.

Silver bromide

Silver bromide (AgBr) is a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light.

Silver carbonate

Silver carbonate is the chemical compound with the formula Ag2CO3.

Silver trifluoromethanesulfonate

Silver trifluoromethanesulfonate, or silver triflate is the triflate (CF3SO3−) salt of Ag+.

See Koenigs–Knorr reaction and Silver trifluoromethanesulfonate

Stereoisomerism

In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
