Abstract:
The conjugate diynylation of α,β-unsaturated trifluoromethyl ketones with terminal diynes is carried out. Pre-metalation of the terminal 1,3-diyne is not required. Diynes bearing a propargylic stereogenic center are obtained with good yields and ee's.

Abstract:
Bis(hexacarbonyldicobalt) complexes of benzyl ether – methyl ether or benzyl ether – acetate derivatives of hepta-2,5-diyne-1,7-diols undergo selective Lewis-acid-mediated Nicholas reactions with enol silanes, silyl ketene acetals, and allylstannanes, preferentially replacing the methyl ether or acetate function. Hydride nucleophiles are similarly incorporated selectively using a benzyl ether – alcohol derivative. Subsequent Nicholas reaction at the benzyloxy-bearing site may be accomplished with an identical or a different nucleophile, affording skipped 1,4-diyne-Co4(CO)12 complexes. In insta

Abstract:
Hyperbranched polyphenylacetylene resins were obtained by the homo-and copolycyclotrimerizations of diynes and monoynes initiated by tantalum-based catalysts, with the aim of exploring new synthetic routes to hyperbranched polyphenylacetylene resins. A group of hyperbranched poly (alkylenephenylenes) (hb-PAPs) were synthesized by TaBr5-Ph4Sn catalyzed polycyclotrimerization of 1,7-octadiyne. To improve the solubility of the homopolymers,the diyne monomers were copolymerized with phenylacetylene. IR,and 1H NMR Spectrum confirmed that the target polymers had formed via a [2+2+2] cyclotrimerizati

1923-1938 Atatürk dönemi dış politikasını bağlantısız bir dış politika diye nitelendirebiliriz. Bu dönemde Türkiye hiçbir büyük güce kendisini bağımlı hissetmemiştir. Zaten dünya ekonomik krizi nedeniyle tüm ülkeler içlerine kapanmak zorunda kalmıştır. Öte yandan kriz nedeniyle güçlenen Faşist İtalya ve Nazi Almanya’sı çevrelerine tehdit oluşturmaya başlamışlar ve bu durum Türkiye’yi komşuları ile daha yakın bir ilişkiye girmesini sağlamıştır. Atatürk özellikle Balkan ülkeleri ile iş birliğine önem vermiş hatta bu iş birliğini Akdeniz’e de yaymak istemiştir. 1939 yılında savaşın başlamasıyla T
