"Addition syn et anti"@fr . . "endo, exo, syn, anti"@en . . . . . "In organic chemistry, syn- and anti-addition are different ways in which substituent molecules can be added to an alkene or alkyne. The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction. The type of addition that occurs depends on multiple different factors of a reaction, and is defined by the final orientation of the substituents on the parent molecule. Syn and anti addition are related to the Markovnikov's rule for the orientation of a reaction, which refers to the bonding preference of different substituents for different carbons on an alkene or alkyne. In order for a reaction to follow Markovnikov's rule, the intermediate carbocation of the mechanism of a reaction must be on the more substituted carbon, allowing the substituent to bond to the more stable carbocation and the more substituted carbon. Syn addition is the addition of two substituents to the same side (or face) of a double bond or triple bond, resulting in a decrease in bond order but an increase in number of substituents. Generally the substrate will be an alkene or alkyne. An example of syn addition would be the oxidation of an alkene to a diol by way of a suitable oxidizing agent such as osmium tetroxide, OsO4, or potassium permanganate, KMnO4. Anti addition is in direct contrast to syn addition. In anti addition, two substituents are added to opposite sides (or faces) of a double bond or triple bond, once again resulting in a decrease in bond order and increase in number of substituents. The classical example of this is bromination (any halogenation) of alkenes. An anti addition reaction results in a trans-isomer of the products, as the substituents are on opposite faces of the bond. Depending on the substrate double bond, addition can have different effects on the molecule. After addition to a straight-chain alkene such as C2H4, the resulting alkane will rapidly and freely rotate around its single sigma bond under normal conditions (i.e. room temperature). Thus whether substituents are added to the same side (syn) or opposite sides (anti) of a double can usually be ignored due to free rotation. However, if chirality or the specific absolute orientation of the substituents needs to be taken into account, knowing the type of addition is significant. Unlike straight-chain alkenes, cycloalkene syn addition allows stable addition of substituents to the same side of the ring, where they remain together. The cyclic locked ring structure prevents free rotation. Syn elimination and anti elimination are the reverse processes of syn and anti addition. These result in a new double bond, such as in Ei elimination."@en .

"Dalam kimia organik, adisi sin dan anti merujuk pada dua cara yang berbeda ketika dua substituen diadisi ke ikatan rangkap dua atau ikatan rangkap tiga. Adisi sin adalah adisi dua substituen pada sisi yang sama (atau muka) dari ikatan rangkap dua atau ikatan rangkap tiga, menghasilkan penurunan derajat ikat namun peningkatan jumlah substituen. Secara umum substrat yang terlibat adalah alkena atau alkuna. Contoh adisi sin adalah oksidasi alkena menjadi diol via oksidator seperti OsO4 atau KMnO4. Adisi anti adalah lawan dari adisi sin. Pada adisi anti, dua subtituen diadisi ke sisi (atau muka) yang berlawanan pada ikatan rangkap dua atau tiga, menghasilkan penurunan derajat ikat namun peningkatan jumlah substituen. Contoh klasik adisi anti adalah brominasi alkena. Tergantung pada ikatan ganda substrat, adisi dapat mempunyai efek yang berbeda pada molekul. Pada alkena berantai tunggal (misalnya etena), setelah adisi, alkana yang dihasilkan akan secara cepat berotasi pada ikatan sigma, sehingga apakah sebuah substituen diadisi pada sisi yang sama atau berlawanan pada ikatan ganda biasanya dapat diabaikan karena rotasi bebas. Namun jika kiralitas atau orientasi substituen diperhitungkan, perbedaan adisi ini sangat signifikan. Berbeda dengan alkena rantai tunggal, adisi sin sikloalkena akan menghasilkan substituen pada sisi yang sama pada cincin dan struktur cincin senyawa ini akan menghalangi rotasi bebas.

Un exemple d'addition syn est l'oxydation d'un alc\u00E8ne en diol par un oxydant adapt\u00E9, tel que le t\u00E9troxyde d'osmium (OsO4) ou le permanganate de potassium (KMnO4) : on parle alors de \u00AB dihydroxylation. \u00BB L'addition anti est l'oppos\u00E9 direct de l'addition syn. Tandis que dans une addition syn, les deux substituants s'additionnent sur les deux extr\u00E9mit\u00E9s et du m\u00EAme c\u00F4t\u00E9 de la liaison multiple, dans une addition anti, les deux substituants s'additionnent sur les deux extr\u00E9mit\u00E9s et de part et d'autre de la liaison multiple. Dans les deux cas, il en r\u00E9sulte une r\u00E9duction de l'ordre de liaison, mais d'une augmentation du nombre de substituants. Un exemple classique est la bromation (ou tout autre halog\u00E9nation) des alc\u00E8nes. Suivant la nature du substrat pour lequel une liaison double est pr\u00E9sente, l'addition peut avoir des effets diff\u00E9rents sur la mol\u00E9cule. Dans le cas d'un alc\u00E8ne \u00E0 cha\u00EEne lin\u00E9aire, l'alcane produit de l'addition pourra rapidement avoir une libre rotation autour de sa liaison simple dans des conditions normales de temp\u00E9rature. En cons\u00E9quence, dans ce cas, cette libre rotation efface toute diff\u00E9rence entre une addition syn ou une addition anti. Ce n'est plus le cas si la mol\u00E9cule est chirale ou si une orientation absolue des substitutions doit \u00EAtre prise en compte, la st\u00E9r\u00E9ochimie sera alors diff\u00E9rente suivant le type d'addition. Contrairement aux alc\u00E8nes lin\u00E9aires, les cycloalc\u00E8nes ne permettent qu'une addition syn, avec les deux subsistants du m\u00EAme c\u00F4t\u00E9, le cycle emp\u00EAchant toute rotation libre. Les \u00E9liminations syn et anti sont les r\u00E9actions inverses des additions syn et anti. Elles r\u00E9sultent en la formation d'une nouvelle liaison double, comme dans l'\u00E9limination Ei."@fr . . .
