AbstractEfforts to prepare 1,6‐dicyano‐2,4‐hexadiyne resulted in the formation of insoluble, chemically inert, high‐melting “brick dust” type polymeric materials. Similar appearing products arose from the dihalo‐, ditosyl‐, and dihydroxy‐ hexadiyne derivatives as well as propargyl halide starting materials. It appears that diacetylenic diols and their propargylic precursors undergo d
