Metal phthalocyanine polymers [PDF]
, 1984 Metal 4, 4', 4", 4"'=tetracarboxylic phthalocyanines (MPTC) are prepared by reaction of trimellitic anhydride, a salt or hydroxide of the desired metal (or the metal in powdered form), urea and a catalyst. A purer form of MPTC is prepared than heretofore.

Total Synthesis of the Cyanobacterial Alkaloid Nostodione A
European Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.The total synthesis of the alkaloid nostodione A is successfully achieved utilizing 3,4‐dihydrocyclopenta[b]indole‐1,2‐dione as a key intermediate. The sensitive benzylidene moiety is introduced via a Knoevenagel condensation with p‐hydroxybenzaldehyde.

Triggering and Preventing Cyclization of o‐Amino‐Guanidinobenzenes to 2‐Amino‐Benzimidazoles
Chemistry – A European Journal, Volume 32, Issue 2, 9 January 2026.o‐Amino‐guanidinobenzenes are generally prone to cyclization to 2‐amino‐benzimidazoles. In this work, strategies to prevent such cyclizations are developed, allowing to use these compounds as ligands in coordination chemistry and for the design of novel (unsymmetrical) redox‐active ligands.

Towards electron transport measurements in chemically modified graphene: The effect of a solvent
, 2010 Chemical functionalization of graphene modifies the local electron density of the carbon atoms and hence electron transport. Measuring these changes allows for a closer understanding of the chemical interaction and the influence of functionalization on ...
