  2. Electrophile - Wikipedia

    en.wikipedia.org/wiki/Electrophile

    The solid-phase reagents were applied toward the selenenylation of various alkenes with good enantioselectivities. The products can be cleaved from the solid support using organotin hydride reducing agents. Solid-supported reagents offers advantages over solution phase chemistry due to the ease of workup and purification.

  3. n-Propylmagnesium bromide - Wikipedia

    en.wikipedia.org/wiki/N-Propylmagnesium_bromide

    Like all Grignard reagents, propylmagnesium bromide is a strong electrophile, sensitive to both water and air. The propylmagnesium halides are the simplest Grignard reagents to exhibit isomerism . Isopropylmagnesium chloride is the primary synthetic equivalent of the isopropyl group .

  4. Electrophilic amination - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_amination

    Alkyl Grignard reagents, [16] alkylithium compounds, [17] alkylzinc compounds, [18] and alkylcuprates [19] have been aminated with electrophilic reagents successfully. Among sp 2-centered carbanions, vinyllithium compounds, [8] vinylcuprates, [20] and vinyl Grignard reagents [21] react with electrophilic aminating reagents to afford enamines.

  5. Williamson ether synthesis - Wikipedia

    en.wikipedia.org/wiki/Williamson_ether_synthesis

    The Williamson ether reaction follows an S N 2 (bimolecular nucleophilic substitution) mechanism. In an S N 2 reaction mechanism there is a backside attack of an electrophile by a nucleophile and it occurs in a concerted mechanism (happens all at once).

  6. N-Bromosuccinimide - Wikipedia

    en.wikipedia.org/wiki/N-Bromosuccinimide

    N-Bromosuccinimide or NBS is a chemical reagent used in radical substitution, electrophilic addition, and electrophilic substitution reactions in organic chemistry. NBS can be a convenient source of Br •, the bromine radical.

  7. Electrophilic fluorination - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_fluorination

    The mechanism of electrophilic fluorination remains controversial. At issue is whether the reaction proceeds via an S N 2 or single-electron transfer (SET) process. In support of the S N 2 mechanism, aryl Grignard reagents and aryllithiums give similar yields of fluorobenzene in combination with N-fluoro-o-benzenedisulfonimide (NFOBS), even though the tendencies of these reagents to ...

  8. Trimethyloxonium tetrafluoroborate - Wikipedia

    en.wikipedia.org/wiki/Trimethyloxonium_tetrafluo...

    Only the exotic dimethylhalonium reagents ([Me 2 X] + [SbF 6] −, X = Cl, Br, I), methyl carboranate reagents, and the transiently-generated methyldiazonium cation (MeN + 2) are stronger sources of electrophilic methyl. Due to its high reactivity, it is rapidly destroyed by atmospheric moisture and best stored in an inert atmosphere glovebox ...

  9. Grignard reaction - Wikipedia

    en.wikipedia.org/wiki/Grignard_reaction

    A solution of a carbonyl compound is added to a Grignard reagent. (See gallery) An example of a Grignard reaction (R 2 or R 3 could be hydrogen). The Grignard reaction (French:) is an organometallic chemical reaction in which, according to the classical definition, carbon alkyl, allyl, vinyl, or aryl magnesium halides (Grignard reagent) are added to the carbonyl groups of either an aldehyde or ...
