Mechanismin classical organic chemistry, two empirical rules, each of limited application, summarize the regularities which have been observed to govern the formation of olefins from alkyl compounds. Hof-mann's rule (an extend Bd form of the rule originally given by Hofmann), applying to primary ...
In organic chemistry, the reaction is in which an atom or a functional group is replaced by another group of atoms or functional groups is called a substitution reaction. Similar to the elimination reaction, the substitution reaction also takes place in two ways. The mechanism is almost similar...

Nucleophilic oxidative addition is similar to SN2 reactions in organicchemistryinvolving apolar compoundsuch as alkylhalide. The incoming A–B compound is attacked at the least electronegative atom by LnM (Eq. (13.14)). Similar to the concerted mechanism discussed above, this type is usually second...
In both cases the solvent adds to the first reaction product, vinyl ether (VI), yielding the same keto-acetal (VII). The mechanism of elimination has been studied by means of isotopic techniques. 展开 DOI: 10.1039/J29690000243 被引量: 2 ...
There is a catch however: the E1 pathway (formation of a primary carbocation) is not the most likely pathway here.Primary carbocations tend to be extremely unstable, and it’s more likely that the reaction passes through an E2 mechanism where the transition state will be lower in energy. No...
FumiyukiOzawa, inCurrent Methods in Inorganic Chemistry, 2003 9.5.2Group 9 and 8 metals Reductive elimination from octahedral complexes of rhodium(III) and iridium(III) has been examined mainly for C–H bond formation. While some of the complexes undergo a dissociative mechanism similarly to plati...
