Rhodium carbonyl-catalyzed cross-hydrocarbonylation of acetylenes and ethylene with carbonmonoxide and hydrogen gives α,β-unsaturated ethyl ketones. Under CO (10 kg cm−2) and H2 (50 kg cm−2) at 90°C the reaction of diphenylacetylene with ethylene in the presence of Rh4(CO)12 catalyst gave (E)-1,2-diphenyl-1-penten-3-one (3a) in 91% yield. Under similar conditions phenylacetylene (1d), 1-hexyne (1e)
羰基铑催化的乙炔和乙烯与一氧化碳和氢的交叉羰基化反应生成α,β-不饱和乙基酮。在90°C下在CO(10 kg cm -2)和H 2(50 kg cm -2)下,在Rh 4(CO)12催化剂存在下,二苯乙炔与乙烯的反应得到(E)-1,2-二苯基-1-戊烯-3-酮(3a),产率91%。在类似条件下,苯乙炔(1d),1-己炔(1e),3,3-二甲基-1-丁炔(1f)和三甲基甲硅烷基乙炔(1g)得到(E)-1-苯基-1-戊烯-3-一个(3d),(E)-4-壬烯-3-一(3e),(E)-6,6-二甲基-4-庚烯-3-一(3f)和(E)-1-三甲基甲硅烷基-1-戊烯-3-一(3g)分别以76%,68%,93%和62%的产率生产。因此,末端乙炔的反应以高的立体选择性和区域选择性进行:将丙酰基引入到空间较少受阻的炔碳原子上。通过将区域选择性与在氢供体例如醇存在下获得的5-乙基-2(5 H)-呋喃酮(2)的

High-purity copper films were deposited at substrate temperatures between 150 and 225 o C via pyrolytic decomposition of a series of alkyne stabilized copper(I) hexafluoroacetylacetonate complexes. The copper-alkyne complexes display varying chemical and physical properties which are dependent upon the identity of the alkyne species used to stabilize the reactive copper(I) moiety. The relationship

[(η5-C5Me4 iPr)2Ln(THF)] (Ln=Sm (8), Yb (9)). The new compounds with the bulky tetramethyl-iso-propylcyclopentadienyl ligands were characterized by C, H analysis, mass spectrometry and NMR spectroscopy. Additionally, single crystal X-ray structure determination of the lutetium complexes 3 and 5 was performed. It has been shown that the alkyl complexes 4–7 are effective precatalysts for the hydrosilylation
