great interest has been focused on gold(III) complexes as cytotoxic and antitumor drugs. Recent studies demonstrated that simple bidentate or polydentateligandscontainingnitrogendonor atoms may offer sufficient redox stabilization to produce viable Au(III) anticancer drug targets under physiologic conditions. So, we have synthesized square planer Au(III) complexes of type [Au(A(n))Clx]·Cly and characterized
A new, convenient and high yielding procedure for the preparation of bis(indolyl)methanes in water by electrophilic substitution reaction of indoles with different carbonyl compounds in the presence of a catalytic amount of [Cu(3,4-tmtppa)](MeSO4)4 (1 mol%) as a highly stable and reusable catalyst is described. This procedure has also been applied successfully for the preparation of bis(pyrazole-5-ols)
pyrrole-unsubstituted dipyrromethanes 1 and boron–dipyrrin (BODIPY) dyes 4 based on a Vilsmeier–Haack reaction. It is highly regioselective and complementary and occurs exclusively at the α- and β-position, respectively, for pyrrole-unsubstituted dipyrromethanes 1 and BODIPYdyes 4. This regioselective formylation enables the syntheses of a variety of α- and β-substituted BODIPYdyes. The installation of formyl groups
A facile method to prepare a reusable copper nanocatalyst is reported.

Selective synthesis of 5-aryl-10-(nitromethyl) substituted 15-azatripyrrane, 15-oxatripyrrane and 15-thiatripyrrane: access to nitromethyl functionalized A<sub>3</sub>B-porphyrins
A chemical strategy toward the selectivesynthesis of unsymmetrical tripyrranes was developed for the formation of meso-aryl and -nitromethyl substituted A3B porphyrins. The iodine catalyzed addition of meso-substituted dipyrromethanes to nitrovinylarenes to generate unsymmetrical 5-aryl-10-(nitromethyl) substituted 15-azatripyrranes, 15-oxatripyrranes and 15-thiatripyrrane under mild conditions has
