Serendipitous desymmetrisation during porphyrazine synthesis: an X-ray crystallographic study of 2,3,7,8,12,13,17,18-octakis(dimethylamino)-2-secoporphyrazine-2,3-dione
Abstract
Linstead macrocyclisation of 2,3-bis(dimethylamino)2(Z)-butenedinitrile gives [2,3,7,8,12,13,17,18-octakis(dimethylamino)porphyrazato]magnesium(II) and the title seco-porphyrazine, the structure of which is established by an X-ray crystallographic study.
