| Questions And Answer | Back Directory | [Synthesis]
First, iodine is used as the initiator to synthesize the Grignard reagent n-pentylmagnesium bromide using magnesium powder. This operation must be performed under strictly anhydrous conditions. Then, it is reacted with 3,4-dihydro-2H-pyran to synthesize 4-penten-1-ol, which is difficult to synthesize by other methods. The synthesis reaction is shown in the figure below:  Figure 4-penten-1-ol synthesis reaction diagram |
