Herein, three different dimethlaminopropyl (DMP) based compounds, namely the previously reported dihydride dimethylaminopropylalane (1, [Al(DMP)H2]), and two new monohydride compounds dimethylaminopropylchloridoalane (2, [Al(DMP)HCl]), and dimethylaminopropylmethylalane (3, [Al(DMP)HMe]) were synthesized. The DMP ligand features an excellent balance of reactivity and stabilization through dative bonding of the amine group, which could be shown previously for the potential TMA substitutes reported by Mai et al. Furthermore, this ligand features decomposition pathways for clean, targeted decomposition as previously shown by Zanders et al., where DMP was employed as ligand for a zinc alkyl reducing agent for ALD of cobalt films.
