For each of the following reactions fill in the box to give the
missing product(s). If no reaction occurs, write N.R. If the
reaction produces a mixture of products, such as stereoisomers or
constitutional isomers, give the structure of each product. If a
major product arises, label it as so. Be sure to show
stereochemistry when needed.
