ABSTRACT:
The present invention relates to novel 2,5-bis{[alkyl (or aryl) imino]aminophenyl}furans and thiophenes of the general formulain which R1, R2, R3and R4are each independently selected from the group consisting of H, alkyl, alkoxy, halide, and alkylhalide groups; R5is H, alkyl or aryl; R6is H, alkyl, aryl, or NR7R8, in which R7and R8are each independently selected from the group consisting of H, alkyl and aryl; and X is O, S or NR9, in which R9is H or alkyl, and to the use of such compounds.
