WebThe reaction of 2-methoxy-1 nitronaphthalene with various Grignard reagents has been examined. Alkylmagnesium halides such as CH3MgBr, PhCH2MgBr, PhCH2CH2MgBr, C2H5MgBr, and i-C3H7MgBr give 1,6-addition products almost exclusively, while PhMgBr gives instead comparable amounts of 1,4- addition and reductive 1,2-addition products. … WebApr 9, 2024 · Note: Ketone reacts with 1 equivalent of Grignard reagent while ester reacts with 2 equivalents of a Grignard reagent to give tertiary alcohol. Since formaldehyde does not contain an alkyl group it is the only aldehyde that gives primary alcohol on reaction with the Grignard reagent. While other aldehydes give secondary alcohol.
