Question
Why is Dialkyl cadmium ($R_2Cd$) synthetically preferred over Grignard reagents ($RMgX$) for converting acyl chlorides directly into ketones?
Answer: B
💡 Solution & Explanation
Grignard reagents are highly reactive nucleophiles and will over-react with the intermediate ketone to form a 3-degree alcohol. $R_2Cd$ is sufficiently mild to safely halt the reaction strictly at the ketone stage.
