Grignard reagents face challenges in synthesizing complex architectures, and quaternary carbon centres remain difficult targets. Now it has been shown that a nickel-catalysed alkene carbomagnesiation strategy, employing a rare contra-electronegativity transmetallation, efficiently synthesizes β-quaternary Grignard reagents with high regio- and enantiocontrol, offering new possibilities for cross-coupling chemistry.
