The Formation of CuCl2-Specific Metallogels of Pyridyloxalamide Derivatives in Alcohols

Isomeric pyridyloxalamide derivatives 1–3, which differed in the position of the nitrogen atom on the pyridyl ring, showed remarkably different gel‐forming aptitudes in the presence of CuCl2 salt in alcohols. Whilst derivatives 1 and 3 formed a soluble complex and a solid precipitate, respectively,...
