Self-assembly of novel trimers using dipyrromethene ligands
Ligands comprising two dipyrromethene units linked at the beta-position have been used to prepare trimeric complexes with Zn-II and Co-II; the structure of the Zn-II complex is confirmed by X-ray analysis.
Heteroleptic zinc dipyrromethene complexes
H-1 NMR spectroscopy has been used to study the complexation of a per-alkyl dipyrromethene with zinc acetate. An intermediate, assigned to be the heteroleptic Zn(dipyrromethene) (acetate) complex, is observed under titration ...
Isolation and characterization of a novel tetrahydro-[2,2 ']bipyrrolyl dimer as an impurity from a Knorr reaction
A novel dimer, tetraethyl 2,2',3,3'-tetramethyl-1,1',2,2'-tetrahydro-4H,4'H-2,2'-bipyrrolyi-5,5,5',5'-tetracarboxylate, has been isolated as an impurity (0.4% yield) from a Knorr reaction for the synthesis of ...
Antimicrobial Activity of Non-natural Prodigiosenes
(RSC Advances, 2013)
Tripyrrolic prodigiosenes, derivatives of the natural product prodigiosin, have been produced via multi-step synthesis beginning with 2-formyl pyrroles bearing various functionalities at the 4-position. Two tin complexes ...
