摘要

Abstract: N-(2-Nitrobenzy1) aza-15-crown-5, 1, and the sidearm hexadeuterio analogue 2 have been reduced electrochemically to their corresponding radical anion forms and analyzed by ESR. Addition of Li', Na', or K'to the solutions leads to changes in the ESR spectra but the changes are most marked when Na'is present Essentially no change is observed in the ESR spectrum of 2-nitrotoluene, confirming that both macroring and ...
