Al(OCArF3)3 - a thermally stable Lewis superacidArF = C6F5.Electronic supplementary information (ESI) available: Experimental procedures as well as computational and crystallographic details are reported in the electronic supplement. CCDC 1818681-1818687, 1863847-1863852 and 1866467. For ESI and crystallographic data in CIF or other electronic format see DOI: 10.1039/c8sc02981d
The adduct free Lewis superacid Al(OCAr F 3 ) 3 was obtained by the reaction of Ar F 3 COH with AlEt 3 and fully characterized (Ar F = C 6 F 5 ). It comprises a high thermal stability up to 180 °C and a distinct reactivity towards Lewis bases, as exemplified by the isolation of the neutral adducts A...
