oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...
A series of triphenylamine-centered starburst quinolines (1a-1g) have been synthesized by Friedländer condensation of the 4,4',4''-triacetyltriphenylamine (2) and 2-aminophenyl ketones (3a-3g) in the presence of catalytic sulfuric acid and characterized well. They are thermally robust with high glass transition temperatures (above 176.4 °C) and decomposition temperatures (above 406 °C). These c...
In general pyrano, pyrazino and simple benzocarbazole derivatives were reported to have phar macological properties like antihistaminic, antiin flammatory, antibiotic and antimicrobial activity [1-11]. Pyridocarbazoles are well known antican cer agents [12-15]. To our knowledge there is no report on the synthesis of quinocarbazoles, which can be considered as substituted pyridocarbazoles, pr...
In Ennead III.5 On Love, Plotinus' discussion of erôs is underlined by Plato’s discourse on love in the Symposium and Phaedrus.[1] Plotinus conceives as a purified power, which directs soul to intelligible realm beauty world Forms.[2] Modern scholarship considers Plotinian an ascending power that always directed higher Forms never lower perceptible realm.
