Copper (II) phthalocyanine and 2, 9, 16, 23 tetrakis nitro copper (II) phthalocyanine has been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalysts over nanodimensional zeolites. 4-Nitro phthalonitrile synthesized from phthaimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis,1H N...

A novel, versatile route to phosphorus- and carbon-substituted η(5)-phosphacyclohexadienyl complexes was developed. Reaction of the anionic 2,4,6-triphenylphosphinine iron complex [K([18]crown-6)(thf)2][Cp*Fe(PC5Ph3H2)] (1) with selected main group element electrophiles afforded the new complexes [Cp*Fe(2-endo-H-PC5Ph3H2)] (endo-3), [Cp*Fe(2-exo-H-PC5Ph3H2)] (exo-3), [Cp*Fe(1-Me-PC5Ph3H2)] (4),...

INTRODUCTION 3-Methylcholanthrene and eight of its metabolites were tested for tumonigenic activity in two tumor models. In the tumonigenicity study on mouse skin, a single topical application of 3 to 30 nmol of compound was followed 7 days later by twice weekly applications of the tumor promotor i 2-0-tetra decanoylphorbol-i 3-acetate for 30 weeks. Comparisons of the percentage of mice with tu...

In the title compound, C(17)H(19)NO(7), the cyclo-pentane ring is in an envelope conformation in which the methyl-ene group forming the flap is cis to the cyclo-propane group. The relative configuration between the 4-nitro-benzo-yloxy substituent on the side chain and the cyclo-propane ring is trans and the methoxy-lmethyl group adopts the expected conformation in which the two O atoms are gauc...

Total suspended particulate matter and fine were collected in five East Asian cities (Sapporo, Sagamihara, Kirishima, Shenyang, Vladivostok) during warm cold periods from 2017 to 2018. Nine polycyclic aromatic hydrocarbons (PAHs) three nitro-polycyclic (NPAHs) detected by high-performance liquid chromatography with a fluorescence detector. The average concentrations of ∑PAHs ∑NPAHs differed sig...
