Abstract

Abstract The thermal reactions (at 120° C) of the 1, 2, 3-selenadiazole 8 with the phosphaalkynes 6a and 6b gave rise to the previously unknown title compounds in 17% and 16% yield, respectively. These compounds are formed by a sequence of [3+ 2]- cycloreversion and cycloaddition reactions.
