The synthesis of new silylethyne-substituted hexacene derivatives to investigate their solubility, stability, and pi-stacking is reported. It was found that "butterfly" dimerization, rather than photooxidation, is the dominant decomposition pathway for these molecules and that stability can be enhanced by functionalization to prevent close contact between specific regions of the aromatic core. ...

Aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [Ir(COD)(PMe3)3]Cl, (COD=1,5-cyclooctadiene), in THF to produce hydridoaminocarboxylato iridium(III) complexes in high yields. These octahedral complexes are formed via oxidative addition reaction of the O-H bond of the carboxylic group with the central metal. The starting iridium(I) complex losses t...

A convenient and efficient application of microencapsulated/methylrhenium trioxide (MTO) and MTO/pyridine systems for the selective oxidation of cardanol derivatives is reported. Environmentally friendly and low-cost H2O2 was used as the oxygen atom donor. The catalysts were stable systems for at least five recycling experiments. In the oxidation of C2 alkyl-substituted cardanol derivatives, hi...

Synthesized of novel metal (II)- tetra-4-(N,N-dimethyl phenyl) methan-imine phthalocyanines (MTDMPhImPc) [ M = Co, Ni, Cu, Zn] by an effective and suitable method. The tetra-nitrophthalocyanines converted into aminophthalocyanines reduction. Than amino derivatives bearing to form tetra substituted 4-(N,N-dimethyl methane-imine complexes. These compounds were characterized FTIR, elemental analys...
