A well-defined Pd(II)-NHC aqua complex for ambient Buchwald-Hartwig amination in tert-butanol

Key Points

• To explore the behavior of Pd(NHC)Cl(allyl/cin) complexes when treated with HCl and their potential for ambient amination.
• Synthesis of Pd(NHC)Cl(allyl/cin) complexes using bulky, electron-rich ligands.
• Treatment of complexes with HCl to observe product formation.
• Analysis of the resulting complexes to determine structural outcomes.
• Expected dimeric species were not formed.
• Novel Pd(II)-NHC aqua complex was identified instead.
• This complex showed potential for application in ambient Buchwald-Hartwig amination.
