N,N'-Persubstituted selenoacrylamides (4), easily available by reaction of 1-chlorovinamidinium salts (2) with sodium selenide, were transformed by means of acceptor-substituted halomethyl compounds (9-14) into new 2-aminoselenophene derivatives (15-20).Their UV/ vis data are presented, and the positive solvatochromism of 2-R2N-5-acceptor-substituted selenophenes is reported.
