or tertiary alcohols from a carbonyl group. The Grignard reaction involves the nucleophilic addition of an organomagenesium complex to a carbonyl carbon followed by acid work-up. This reaction involves a single electron transfer between the carbonyl group and the grignard reagent. Once the Grignard reagent is synthesized it can work as a base by abstracting a proton or it can work as a good nucleophile. When it works as a base it can be added to water‚ alcohols‚ amines‚ acids‚ terminal alkynes and
