The study of asymmetric phosphine compounds and their applications and the appearance of various novel compounds have greatly enriched organophosphorus chemistry. Phosphorus-containing antioxidants, stabilizers, and extractants and complexing agents used as rare elements have been widely used in the chemical industry. The organic phosphine compound in the organism is an important energy source and an important component in the formation of biopolymer DNA and RNA backbone. Organophosphorus compounds in nucleic acids, coenzymes, organophosphorus toxic gases, organophosphate insecticides, organophosphorus bactericides, organophosphorus herbicides, chemotherapeutic agents, plasticizers, antioxidants, surfactants, complexing agents, organophosphorus It is widely used in extractants, flotation agents and flame retardants. The chemical structure of organic phosphine compounds can be roughly classified into the following categories: 1. Phosphonates. Phosphoric acid is a tribasic acid, that is, three hydrogen atoms which can be replaced. These hydrogen atoms are replaced by organic groups, called phosphonates. When these three groups are not identical, they are called mixed esters. Many of the pesticides are mixed esters of phosphoric acid, such as dichlorvos, which is a mixed ester of phosphoric acid. 2. Thio, dithio and trithiophosphonates. The oxygen atom in the phosphate molecule is replaced by a sulfur atom, which is called a thiophosphonate, such as parathion, dimethoate, and rice blast. 3. Phosphoramide and thiophosphoramide. The hydroxyl group in the phosphoric acid molecule is replaced by an amino group, which is called phosphoramide. The remaining oxygen atom in the phosphoramide molecule may be replaced by a sulfur atom to become a thiophosphoramide such as methamidophos or fertile phosphorus. 4. Pyrophosphonates, thiopyrophosphonates and pyrophosphamides. The two phosphoric acid molecules remove one molecule of water to form pyrophosphoric acid, and the hydrogen, oxygen and hydroxyl groups in the pyrophosphate can also be replaced by an organic group, a sulfur atom and an amino group, respectively, such as a phosphorus. 5. Phosphonates and thiophosphonates. One of the hydroxyl groups in the phosphoric acid is replaced by an organic group, that is, a PC bond is formed in the molecule called a phosphonic acid, and some phosphonic acids and sulfur-substituted compounds thereof have been promoted as pesticides, such as phoxim. 6. Derivatives of phosphorous acid. Some pesticides are derivatives of phosphorous acid. In the molecule of phosphorous acid, phosphorus is trivalent, such as defoliation. 7. Phosphine. When the hydrogen in the phosphine molecule is replaced by an organic group, it is called a phosphine. The structures of these compounds are similar to those of the nitrogen compounds ammonia, amine and ammonium salts, and are called phosphines and ortho-phosphines. 8. The hydroxyl group in the phosphoric acid or phosphonic acid molecule is replaced by a halogen.
