Kuzuya, Masayuki published the artcileA novel single electron transfer in solid-state organic compounds: mechanically induced reduction of dipyridinium salts, Related Products of pyridine-derivatives, the publication is Journal of Physical Chemistry (1993), 97(30), 7800-2, database is CAplus.
When mech. vibration (56 Hz) of dipyridinium dications I (R = Me, R1 = cyano, X = Br; R = Ph, R1 = H, X = Cl; R = Me, R1 = H, X = Cl), II (n = 2, 3, 4), and III (100 mg each) was conducted with a stainless steel ball (6.0-mm diameter, 890 mg) in a stainless steel twin-shell blender (7.8-mm diameter, 24 mm long) for 30 min at room temperature under strictly anaerobic conditions, the powder surfaces of all I and of II (n = 2) turned deep blue-purple, and nearly isotropic broad single-line ESR spectra were observed in the resulting powders, which can be ascribed to the formation of the corresponding monocation radicals via solid-state single electron transfer (SSET). Facile intermol. SSET also occurred from the monocation radical of I (R = Me, R1 = H, X = Cl) to I (R = Ph, R1 = H, X = Cl) and to II (n = 4). The mech. induced SSET reported herein seems to be a general phenomenon with broad implications for many organic compounds with relatively low redox potentials and is of special significance in connection with manufacturing a variety of solid materials in pulverized form in a metallic vessel.
