环加成

Cycloaddition

环加成是周期性化学反应,其中“两个或多个不饱和分子结合形成环状加合物,其中存在键多重性的净减少”。 所得反应是环化反应。 许多但不是所有的环加成都是协调一致的。 作为一类加成反应,环加成允许碳 - 碳键形成而不使用亲核试剂或亲电子试剂。 可以使用两种符号系统来描述环加成。 较老的但仍然常见的符号是基于反应物中原子的线性排列的大小。 它使用括号:其中变量是每个反应物中线性原子的数量。 该产品是一个大小的循环。 在该系统中,标准Diels-Alder反应是环加成,1,3-偶极环加成是卡宾与烯烃环加成的环加成和环丙烷化反应。 最近,IUPAC优选的符号使用方括号表示涉及产物形成的电子数,而不是碳原子数。 在标记中,标准Diels-Alder反应是环加成,1,3-偶极环加成是。 A cycloaddition is a pericyclic chemical reaction, in which "two or more unsaturated molecules combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity." The resulting reaction is a cyclization reaction. Many but not all cycloadditions are concerted. As a class of addition reaction, cycloadditions permit carbon–carbon bond formation without the use a nucleophile or electrophile. Cycloadditions can be described using two systems of notation. An older, but still common, notation is based on the size of linear arrangements of atoms in the reactants. It uses parentheses: where the variables are the numbers of linear atoms in each reactant. The product is a cycle of size. In this system, the standard Diels-Alder reaction a cycloaddition, the 1,3-dipolar cycloaddition is a cycloaddition and cyclopropanation of a carbene with an alkene a cycloaddition. A more recent, IUPAC-preferred notation uses square brackets to indicate the number of electrons, rather than carbon atoms, involved in the formation of the product. In the notation, the standard Diels-Alder reaction is a cycloaddition, the 1,3-dipolar cycloaddition is.
