Preparations of the title compounds, 5–7 (Scheme 1 and Table 1), of their ammonium salts, 9–11 (Scheme 2 and Table 2), and of the corresponding cinnamaldehyde‐derived iminium salts 12–14 (Scheme 3 and Table 3) are reported. The X‐ray crystal structures of 15 cinnamyliminium PF6 salts have been determined (Table 4). Selected 1H‐NMR data (Table 5) of the ammonium and iminium salts are discussed, and...
