الوصف

Niobium is a compound in which pyrrole is connected in parallel with benzene. Also known as benzopyrrole. There are two ways of combining. Earthworms and their homologues and derivatives are widely found in nature and are found mainly in natural flower oils such as jasmine, bitter orange, daffodil, fragrant orchids and the like. For example, strontium was firstly degraded by indigo; strontium and its homologues were also found in coal tar; essential oils (such as jasmine essential oils) also contained strontium; feces contained 3-methyl hydrazine; The dye is a derivative of hydrazine; an essential amino acid of the animal, tryptophan, is a derivative of hydrazine; certain physiologically active natural substances, such as alkaloids, auxins, etc., are derivatives of hydrazine. Bismuth is an imine, which has a weak basicity; the double bond of a heterocyclic ring generally does not undergo an addition reaction; under the action of a strong acid, dimerization and tripolymerization can occur; under special conditions, aromatic electrophilicity can be performed. In the substitution reaction, hydrogen at the 3-position is preferentially substituted, and if reacted with a sulfonyl chloride, 3-chloroindole can be obtained. A variety of reactions can also occur at the 3-position, such as the formation of Grignard reagents, condensation with aldehydes, and Mannich reactions.
