Stereospecific - Chemistry LibreTexts
网页2022年2月28日 — Reactions 3 and 4 are Diels-Alder reactions of stereoisomeric dienophiles 5 and 6 with the same diene, 1,3-butadiene. The products of the reaction of 5 is 7; the products of the reaction of 6 are 8 and 9. 7 and 8 are stereoisomers, so are 7 and 9. Thus, Diels-Alder reactions are stereospecific. see stereoselective.
Stereospecificity - Wikipedia
网页In chemistry, stereospecificity is the property of a reaction mechanism that leads to different stereoisomeric reaction products from different stereoisomeric reactants, or which operates on only one (or a subset) of the stereoisomers. [1][2][3]
Stereospecific vs Stereoselective Reactions - Organic Chemistry …
网页Many reactions we cover in the organic chemistry are stereospecific. When you hear the word “stereospecific” you should think about the “syn” and “anti” addition reactions. While there are other types of stereospecific reactions in organic chemistry, we traditionally only cover a few of those within the scope of the course.
Stereoselective vs. Stereospecific Reactions - ChemTalk
网页The fundamental difference between stereospecific and stereoselective reactions lies in the precision and exclusivity of stereoisomer formation. Stereospecific reactions yield a single stereoisomer as the sole product, while stereoselective reactions favor one stereoisomer over others but can still produce a mixture of stereoisomers.

网页2010年7月2日 — According to IUPAC, a stereospecific reaction is one where starting materials differing only in their configuration are converted into stereoisomeric products. The S N 2 reaction is an example of a stereospecific reaction.

网页stereospecific. In a stereospecific chemical reaction, the position of the atoms within the molecules (= a unit of a chemical substance made of a group of two or more atoms) …
网页Stereospecific. A reaction is termed stereospecific if, in such a reaction, starting materials differ only in their configuration are converted to stereoisomerically distinct products. According to this definition, a stereospecific process is necessarily stereoselective, but stereoselectivity does not necessarily imply stereospecificity.
Stereospecific - Vocab, Definition, and Must Know Facts - Fiveable
网页Stereospecific reactions in organic chemistry are reactions where the configuration of the reactant determines the configuration of the product, with respect to the spatial arrangement of atoms. These reactions follow a predictable pattern, particularly noticeable in processes like the addition of carbenes to alkenes, leading to specific ...
