Question

Curved arrows are used to illustrate the flow of electrons. Using the provided starting and product structures, draw the curved electron pushing arrows for the following reaction or mechanistic steps. Be sure to account for all bond-breaking and bond-making steps.

The image contains a series of hand-drawn chemical reaction mechanisms illustrating a multi-step synthesis process. Each step includes molecular structures and placeholders labeled "add arrows here" indicating where reaction mechanism arrows should be drawn. Below is a detailed description of each part:

1. **Top Left Box:**
   - Reactants: Benzyl ketone and diethylamine.
   - Mechanism step: A proton transfer is implied but not shown. Curved reaction arrows need to be drawn to show electron movement.

2. **Top Right Box:**
   - Intermediate: Formation of an iminium ion from benzyl ketone and diethylamine.
   - Mechanism step: The process continues with further interaction, suggesting nucleophilic attack which needs to be depicted with arrows.

3. **Middle Left Box:**
   - Intermediate: Hydroxylamine derivative after dealing with the iminium ion.
   - Mechanism step: Indication to add arrows for the nucleophilic attack or rearrangement.

4. **Middle Right Box:**
   - Intermediate: Shows another step with a structural rearrangement.
   - Mechanism step: Requires additional arrows to show the progression of the reaction.

5. **Bottom Left Box:**
   - Intermediate: Further modification of the structure, possibly indicating an elimination or substitution.
   - Mechanism step: More arrows needed to clarify the reaction pathway.

6. **Bottom Right Box:**
   - Final Product: Formation of a cyclic aminal or similar structure.
   - Mechanism step: Add arrows illustrating the final transformation steps to the product.

Overall, this document serves as a guide for students to practice drawing mechanistic arrows that show the flow of electrons during chemical reactions. The handwritten instructions encourage active engagement in learning organic reaction mechanisms by filling in the missing parts of each step.
