Abstract
Abstract: The magnetic interaction of the two triplet phenylnitrene units linked together through an acetylene or a diacetylene linkage has been investigated by ESR spectroscopy. Two regioisomeric (meta, para'and meta, meta') diazides of 1, 2-diphenylacetylene 12a and 1, 4-diphenyI-l, 3-butadiyne 13a were prepared and photolyzed in a 2-methyltetrahydrofuran glass at IO K to give the corresponding dinitrenes 12n and 1311. The m, p'-dinitrenes of ...
