Air-sensitive complexes [Cu2(μ-phtz)3(PR3)2][CF3SO3]2 (phtz = C8H6N2), 3 (R = phenyl) and 4 (R = benzyl) have been synthesized from {[Cu(CF3SO3)]2·C6H5Me} (1) at room temperature, in acetonitrile solution, after successive additions of stoichiometric amounts of phthalazine (phtz) and triphenylphosphine and tribenzylphosphine, respectively. The dissolution of 4 in an excess of benzyl chloride ga...

Chemiluminescence (CL) of a cyclometallated iridium (III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III)} in the presence of potassium permanganate and oxalic acid is reported for the first time. Cysteine exhibits sufficient enhancing effect on the CL generated from the cyclometallated iridium(III) complex, which make it possible for the sensitive detection of ...

pb(oac) /cr0 combination was found to be able to oxidize methylene dioxide function in the presence of diphenylmethane moiety

A series of cycloalkene-annelated phthalazin-1(2H)-ones (2-5) was prepared in high yields by a one-pot procedure, employing pyridazino[4,5-d]pyridazin-1(2H)-ones (1) as azadienes and cyclic enamines as dienophiles in an inverse-electron-demand Diels-Alder reaction, followed by acid-catalyzed aromatization. Phthalazin-1(2H)-ones bearing a substituent at C-4 represent key intermediates in the syn...
