The preparation of phosphininium salts form phosphinines by protonation or alkylation fails, while the generation of pyridinium salts from pyridine succeeds. Presumably, the reason for this is the opposite distribution of the electrons in the two ring systems. It has now been possible, for the first time, to obtain a stable phosphininium salt 2 by reaction of phosphinine 1 with AlCl 3 .
