Curved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the curved arrows to draw the intermediate and product of this reaction or mechanistic step(s). Include all lone pairs and charges as appropriate. Use wedges and dashes to indicate stereochemistry. Ignore inorganic byproducts.
