vicinal dihalides undergoes the reaction with strong
base and forms the alkyne is the final product , here in the
mechanism the hydrogen and the halogen must be in anti to each
other and after first halogen removed and then it forms the double
bond and the wedge dash representation is not taken simply write
the elements because it is not a chiral center

CONCEPT QUESTIONS Mechanism. While the reaction carried out in lab used potasslum hydroxide as the catalyst, many other catalysts have been developed to increase regioselectivity and stereoselectivity in aldol condensations. One small molecule catalyst commonly used is proline, a naturally occurring amino acid. The mechanism invoives the initial formation of an enamine; predict the structure of this enamine intermediate (Intermediate A), and draw the mechanism for the conversion of intermediate A to Intermediate B. Helpful Hint: The formation of the...
