The title compound, [Ni(C(60)H(52)N(4))], is an example of a meso tetra-substituted nickel(II) porphyrin with both meso aryl and alkyl residues. The mol-ecule exhibits a planar macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane (Δ24) of 0.01 Å and an average Ni-N bond length of 1.960 (2) Å. The Ni(II) atom lies on a center of inversion. The structure ...

The complete molecule of the title compound, [Cu2(C2H3O2)2(CF3O3S)2(C12H8N2)2], is completed by the application of a twofold rotation and comprises two Cu(II) ions, each of which is penta-coordinated by two N atoms from a bidentate 1,10-phenanthroline (phen) ligand, two O atoms from acetate ligands and an O atom from a tri-fluoro-methane-sulfonate anion, forming a (4 + 1) distorted square-pyram...

[structure: see text]. Increased efficiency for ring-closing metathesis to form tetrasubstituted olefins using N-heterocyclic carbene ligated ruthenium catalysts was achieved by reducing the size of the substituents at the ortho positions of the N-bound aryl rings.

Organic conjugated compounds containing various substituents 3-amino-2,4-dicyano-1-aryl-9H-fluorene and 1-dicyanomethylene-2-aryl-indone derivatives were successfully obtained. Various routes synthesis methods, such as one-pot, multi-step, microwave irradiation (MWI), explored for efficiency. Spectroscopic methods used to characterize of the synthesized compounds. Furthermore (E)-2-(2-(anthrace...

10 aryl propylene oxides and 6 aryl butylene oxides were synthesized. Dose-mutagenicity relationships were studied for these compounds and for 1,2-epoxybutane, using both the preincubation and plate incorporation Ames tests with Salmonella typhimurium strains TA100 and TA1535. Structure-mutagenicity relationships were further examined by concurrent testing at single doses with the plate incorpo...
