Abstract
Simple 2H-chromenes and W-thiochromenes form the [2+2]-adducts, trahyd ro[1]benzo(thio)pyrano[3,4-c][1,2]diazeto[1, 2-a][1,2,4] triazoles, wi th triazolinediones, whereas their 3- and 4-bromo and the correspondin g cycloalkylamino derivatives undergo an overall electrophilic substit ution sequence.
