Phosphoramidates are for the first time presented as efficient N-Centered Radical (NCR) precursors under visible-light irradiation. More precisely among this class of phosphorus-derived compounds, we studied the radical reactivity of phosphonohydrazones, under mild reaction conditions, which allowed the synthesis of a wide and diversified library of the scarcely reported phthalazine scaffold. Mechanistic investigations confirmed the formation of a NCR from these brand-new phosphonohydrazones (derivatived from phosphoramidates), which were further engaged in an intramolecular 6-exo-dig cyclization to provide phthalazines. Compared to other pre-activated moieties, the phosphoramidate group is self-immolative, thus enhancing its attractiveness for the C-N bond formation.

In a document, author is Soliman, Saied M..

A novel route for the synthesis of Cu(II)-triazolophthalazine complexes using the Cu(II)-promoted cyclization dehydrogenation reactions of hydrazonophthalazines under reflux was presented. Two hydrazonophthalazines were cyclized to the corresponding triazolophthalazine ligands, 3-pyridin-2-yl-3,10b-dihydro-[1,2,4]triazolo[3,4-a]phthalazine (TPP) and 3-(3,10b-dihydro-[1,2,4]triazolo[3,4-a]phthalazin-3-yl)-benzoic acid (TP3COOH), followed by in situ complexation with Cu(II) yielding six novel Cu(II)-triazolophthalazine complexes depending on the reaction conditions. The molecular and supramolecular structures of the Cu(II)-triazolophthalazine complexes were discussed. The metal sites have rectangular pyramidal geometry in the [Cu(TPP)Cl-2](2); 1 and [Cu(TP3COOEt)Cl-2(H2O)](2); 4 dinuclear complexes, distorted square planar in [Cu(TP3COOMe)(2)Cl-2]; 3, [Cu(TP3COOH)(2)Cl-2]; 5 and [Cu(TP3COOH)(2)Cl-2]center dot H2O; 6 and a distorted octahedral in [Cu(TPP)(H2O)(2)(NO3)(2)]; 2. Hirshfeld analysis showed that the O horizontal ellipsis H, C horizontal ellipsis H, Cl horizontal ellipsis H (except TP3COOH and 2), N horizontal ellipsis H and pi-pi stacking interactions are the most important intermolecular contacts. The pi-pi stacking interactions are the maximum for TP3COOH and complex 6 with net C horizontal ellipsis C/C horizontal ellipsis N contacts of 19.4% and 15.4%, respectively. The orbital-orbital interaction energies of the Cu-N/Cu-Cl bonds correlated inversely with the corresponding Cu-N/Cu-Cl distances, respectively. The charge transfer processes between Cu(II) and ligand groups were also discussed. The charge densities of the Cu(II) centers are reduced to 0.663-0.995 e due to the interactions with the ligand groups coordinating it.
