چکیده

A tungsten neopentylidene complex has been found to decompose to yield a heterochiral dimer that contains a W=W double bond and no bridging ligands. Decompositions of related bisalkoxide complexes also yield compounds that contain an "unsupported" W=W double bond, while a sample of [Mo(NAr)(CH2-t-Bu)(OC6F5)]2 has been found to be a homochiral species related to [W(NAr)(CH2-t-Bu)(OC6F5)]2.

Organometalltc Complexes of Tungsten and Tantalum: Synthesis, Structure and Reactivity Lourdes Pia H. Lopez

Chapter 1 W(NAr)(CH-t-Bu)(CHz-t-Bu)? (Ar = 2,6-i-Pr2ChH3) was synthesized in four steps starting from WC16. The reaction of W(NAr)(CH-t-Bu)(CH2-t-Bu)? with various alcohols (1-AdamantylOH, t-BuOH, ArOH, (CF3)?CHOH, (CF3)2MeCOH, CF3Me2COH, (CF3)3COH, C6F50H) in hydrocarbon solvents gave either W(NAr)(CH-t-Bu)(CH?-t-Bu)(OR) or W(NAr)(CH2t-Bu);(OR) depending on the pK, of the alcohol used. W(NAr)(...

Homogeneous and heterogeneous oligomerization reactions of olefins with unbridged metallocene catalysts

1-Pentene, respectively 1-hexene, were reacted with 13 homogeneous metallocene catalysts to give linear oligomerization products, predominantly dimers, with selectivities above 90%. The product distributions of the codimerization reactions of 1-pentene with 1-hexene reflected a binomial behaviour. Therefore, the ratio for dimers is 1:2:1 (C10:C11:C12) while the trimers (pentadecenes up to octad...

Systematic variation of metal-metal bond order in metalloporphyrin dimers.

A general method for synthesizing a novel class of metalloporphyrin dimers containing unbridged metal-metal bonds is presented. By choosing the appropriate metal, the bond order in these dimers can be varied systematically. The synthesis and characterization of osmium(II) and molybdenum(II) porphyrin dimers containing the respective metal-metal double and quadruple bonds are described. A simple...

Platinum-oxygen Bond Formation: Kinetic and Mechanistic Studies

Reaction of [PtMe(C^N)(SMe2)] (C^N = 2-phenylpyridinate (ppy); 1a, C^N = benzo[h]quinolate, (bhq); 1b) with hydrogen peroxide gives the platinum(IV) complexes trans-[PtMe(OH)2(C^N)(H2O)] (C^N = ppy; 3a, C^N = bhq, 3b) bearing platinum-oxygen bonds. The Pt(II) complexes 1a and 1b have 5dπ(Pt)→π*(C^N) MLCT band in the visible region which is used to easily follow the kinetic of its reaction with ...

Effect of cropping system on cotton biomass accumulation and yield formation in double–cropped wheat–cotton

Wheat–cotton double cropping practices on a large scale in cotton belt of the Yellow RiverValley and the Yangtze River Valley in China. Field experiments were conducted to determinethe effects of wheat–cotton double cropping on cotton biomass accumulation and yieldformation during 2011/12 and 2012/13 growing seasons. Two cotton cultivars, Siza 3 (mid–latematurity) and CCRI 50 (early maturity), ...
