The electrochemical behavior of 5 1h pyrromethenones and 3 4 dihydro 5 1h pyrromethenones



The electrochemical behavior of 5 1h pyrromethenones and 3 4 dihydro 5 1h pyrromethenones



Monatshefte fuer Chemie 116(5): 681-684



Cyclic voltammetry and polarography measurements in anhydrous dimethylformamide indicate that 1,3,4,5-tetrahydro-3-methoxycarbonylmethyl-3',4,4,4'-tetramethyl-5-oxo-2,2'-pyrromethen-5'-carboxylic acid tert-butylester [a 3,4-dihydro-5(1H)-pyrromethenone] is both easier to reduce and to oxidize than structurally related 5(1H)-pyrromethenones.
