Beyond transition block metals: exploring the reactivity of phosphine PTA and its oxide [PTA(O)] towards gallium(iii).

ABSTRACT: The water-soluble cage-like phosphine PTA (1,3,5-triaza-7-phosphaadamantane) and its phosphine oxide derivative [PTA(O)] (1,3,5-triaza-7-phosphaadamantane-7-oxide) were used to explore their reactivity towards two gallium(iii)-halide precursors, namely GaCl₃ and GaI₃, for the first time. By using various reaction conditions, a series of N-mono-protonated phosphine salts with [GaCl₄]^- or [I]^- as counterions were obtained in all cases, while the formation of coordinated Ga-PTA and Ga-[PTA(O)] complexes was not observed. All compounds were characterized in solution using multinuclear NMR spectroscopy (¹H, ¹³C{¹H}, ³¹P{¹H} and ⁷¹Ga) and in the solid state using FT-IR
