The reaction between bis(2-benzothiazolyl)ketone and vinyl grignard reagents bearing different substituents on the vinyl moiety gave the product derived from attack on the carbonylic carbon- and/or oxygen-atom. the regioselectivity of the attack depends on the kind of substituents bound to the vinylic carbon atoms and on their relative position. the reaction between vinylmagnesium bromide and ..., a grignard reagent or grignard compound is a chemical compound with the generic formula r−mg−x, where x is a halogen and r is an organic group, normally an alkyl or aryl.two typical examples are methylmagnesium chloride cl−mg−ch 3 and phenylmagnesium bromide (c 6 h 5)−mg−br.they are a subclass of the organomagnesium compounds. grignard compounds are popular reagents in organic ....

The grignard reaction produces a carbon–carbon bond. it alters hybridization about the reaction center. the grignard reaction is an important tool in the formation of carbon–carbon bonds. it also can form carbon–phosphorus, carbon–tin, carbon–silicon, carbon–boron and other carbon–heteroatom bonds., the reaction of an organic halide with magnesium is not a grignard reaction, but provides a grignard reagent. [5] grignard reactions and reagents were discovered by and are named after the french chemist françois auguste victor grignard ( university of nancy , france), who published it in 1900 and was awarded the 1912 nobel prize in chemistry for this work..

Bei der grignard-reaktion [ɡriˈɲaːr-] handelt es sich um eine namensreaktion in der organischen chemie, welche nach ihrem entdecker, dem französischen chemiker victor grignard benannt wurde, der für diese entdeckung 1912 mit dem nobelpreis ausgezeichnet wurde. die grignard-reaktion ist eine metallorganische chemische reaktion, bei der alkyl- oder aryl-magnesiumhalogenide (siehe grignard ...
