We explore the chemistry of Lewis acids based on aluminium and phosphorus. Aluminium-bis(triflate) compounds, when activated with Na[BArCl4] (ArCl = 3,5-Cl2-C6H3), showed remarkable activity with respect to several Diel Alder transformations. We succeeded in crystallographic characterization one of these systems that was identified as a 2-D coordinational polymer. Our recent reports on a coordinatively saturated P(III)-centered dication and its reactivity toward water and methanol were further expanded with the unusual reactivity with pyridine N-oxide resulting in the P-C bond oxidation. Also, we showed that these compounds are capable of C-F activation. Lastly, according to DFT studies we stumbled upon a reaction that involved sterically induced P-N bond cleavage.
