BuMoN(i-Pr)(2) is shown to be kinetically and thermodynandcally efficient for deprotonation/magnesiation cis and beta to an activating carboxamido group on a cyclobutane ring. The resulting carboxamido-stabilized amido-Grignards are useful reagents. The method provides an entirely new approach to controlled substitution on cyclobutanes. BuMaN(i-Pr)(2) will also metalate pivaloyl amides.
