—— | 2-((5-methylthiophen-2-yl)methylene)malononitrile | 81020-77-1 | C9H6N2S | 174.226 |
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.
