Electrophiles are electron deficient species which has positive or partially positive charge. Lewis acids are electrophiles which accept electron pair.
>
Nucleophiles are electron rich species which has negative or partially negative charge. Lewis bases are nucleophiles which donate electron pair.
>
Grignard reagent or RMgX can be synthesized from haloalkanes by reacting them with magnesium in the presence of dry ether.
>
Phosphorus ylides can be prepared from alkyl halides on reaction with triphenyl phosphine in the presence of a strong base, such as butyl lithium.
>
Grignard reagent or phosphorus ylides react with carbonyl compounds to form alcohols and alkenes, respectively.
>
Treatment of epoxides with Grignard reagent results in the formation primary alcohols.
>
The Grignard reagent or RMgX is a polar organometallic reagent that undergoes nucleophilic addition reaction with aldehydes and ketones. It contains organic group which is covalently bonded to magnesium atom, which is also bonded to halogen atom.
