WebOct 29, 2024 · As I understand it, Grignard reagents are strong nucleophiles and will readily attack any electrophilic centers. If so, how would a reagent having the formula RMgX react with a phosphoric acid derivative ( R X 1) ( R X 2) ( R X 3) P = O, where R X 1, R X 2, and R X 3 can be either alkyl, alkoxy, − O H, or − H? WebJan 23, 2024 · Reactions of Grignard reagents with aldehydes and ketones. These are reactions of the carbon-oxygen double bond, and so aldehydes and ketones react in exactly the same way - all that changes are the groups that happen to be attached to the carbon … The reaction happens at room temperature, and takes place in two separate stages. … jeong junha
