N,N-Bis(diphenylphosphino)ethylaniline compounds, [Ph2P](2)N-C6H4-C2H5, with ethyl groups at the ortho- and para-positions have been synthesized. Oxidation of the aminophosphines with hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides [Ph2P(E)](2)N-C6H4-C2H5 (E = O, S, Se). Complexes [MCl2{(Ph2P)(2)N-C6H4-(C2H5)}] (M = Pd, Pt) and [Cu{(Ph2P)(2)N-C6H4-C2H5)(2)]PF6 were obtained by the reaction of NN-bis(diphenylphosphino)ethylaniline with [MCl2(COD)] (M = Pd, Pt) and (Cu(MeCN)(4)]PF6. The new compounds were characterized by NMR, IR spectroscopy and microanalysis. In addition, representative solid-state structures of the palladium and platinum complexes were determined using single crystal X-ray diffraction analyses.

Crosslinking of Trimethylene Carbonate and D,L-Lactide (Co-) Polymers by Gamma Irradiation in the Presence of Pentaerythritol Triacrylate
Bat, Erhan; Feijen, Jan; Grijpma, Dirk W. (Wiley, 2011-07-07)
High-molecular-weight (co) polymers of trimethylene carbonate and D, L-lactide are efficiently crosslinked using PETA during gamma irradiation. Form-stable networks with gel contents of 86 +/- 5 to 96 +/- 1 are obtained from non-crystalline (co) polymers. Glass transition temperatures and elastic moduli of the networks can be varied by adjusting the copolymer composition. The PETA-containing (co) polymer networks are not cytotoxic. Upon incubation in macrophage cultures for 14 d, all (co) polymer films and ...
Synthesis, characterization, and electrochemistry of tetracarbonyl(6-ferrocenyl-2,2 '-bipyridine)tungsten(0)
Edinc, Pelin; Oenal, Ahmet M.; Özkar, Saim (Elsevier BV, 2007-04-15)
6-Ferrocenyl-2,2'-bipyridine (fcbpy) was prepared by the reaction of lithiated ferrocene with bipyridine and employed as a bidentate ligand for the formation of tetracarbonyl(6-ferrocenyl-2,2'-bipyridine)tungsten(0). The labile complex pentacarbonyl[eta(2)-bis(trimethylsilyl)ethyne]tungsten(0) reacts with fcbpy in CH2Cl2 to yield the disubstitution product, W(CO)(4)(fcbpy), which was isolated as analytically pure substance and characterized by elemental analysis, IR, UV-Vis, MS, H-1 and C-13 NMR spectroscop...

Comparative vegetative anatomy of the tribe triticeae dumortier (poaceae) in Turkey
Mavi, Dudu Özlem; Doğan, Musa; Department of Biology (2012)
Triticeae Dumort. is a tribe within the Pooideae subfamily of Poaceae. Major crop genera found in this tribe include barley (Hordeum), wheat (Triticum) and rye (Secale) all of which are closely related to each other. In Turkey, with the several subgroups, this tribe is represented by 16 genera and 75 species, many of which have great economic values. The main objective of this research work is to determine the taxa of this tribe on the basis of their diagnostic anatomical characters of vegetative organs for...
