Organometallic derivatives

Ziegler catalysts Complex catalysts prepared by interaction between an organometallic derivative and a transition metal derivative. A typical catalyst is the product of the interaction of TiCU and AIBU3. These catalysts polymerize olefins, particularly ethylene, to polyolefins, the polymerization generally being in a siereoregular manner. [Pg.432]

The preparation of aromatic fluorine compounds may be accomplished by direct fluorination or by fluonnation of organometallic intermediates. Tlte ipso fluorination of an aryl organometallic derivative with a positive fluorine reagent allows control over the regioselectivity of the fluorination and offers advantages in the preparation of F-labeled materials [II, 50],... [Pg.148]

The most ionic of the organometallic derivatives of Group 1 elements are the acetylides and dicarbides formed by the deprotonation of alkynes in liquid ammonia solutions ... [Pg.103]

Organometallic derivatives M2R4 are rather more stable than the hydrides and, indeed, dicacodyl, Me2AsAsMc2, was one of the very first organometallic compounds to be made... [Pg.583]

Compounds prepared from naturally occurring nucleosides are of course more closely related to genetic material and may have a better chance of interacting with infected cells. Mercu-ration of the 2 -dcoxyuridine 113 leads to the organometallic derivative 114 reaction of that with ethylene in the presence dilithio palladium tetrachloride gives the alkylation product 115 this is reduced catalytically in situ. There is thus obtained the antiviral agent edoxudine (116) [25]. [Pg.117]

Unsolvated organomagnesium compounds have been recommended for the synthesis of organometallic derivatives of mercury, boron, aluminum, silicon, germanium, tin, phosphorus, arsenic, and antimony6-8 and have been used in procedures for the alkylation of aromatic rings and for the production of various polymerization catalysts.4 9... [Pg.117]

The preparation of aryl- and heteroaryltrimethylsilanes has been comprehensively reviewed ( /). In practice, these silanes are prepared most frequently by the quenching of a suitable organometallic derivative with TMSC1 ... [Pg.114]

A second class of organometallic derivatives, namely alkyllithium reagents, has been condensed onto aldehydes in the presence of chiral sulfur-containing... [Pg.147]

The alkyl complexes [TpBut]MgR (R = Me, Et, Pr , Bul) react with excess 02 at room temperature to give alkylperoxo complexes [TpBut]-MgOOR (Scheme 5), which have been characterized by 170 NMR spectroscopy. Each complex exhibits two 170 NMR resonances in the ranges 8 102-183 and 8 323-427 for the two distinct oxygen atoms of the alkylperoxo (Mg-O-O-R) moiety (Table IV). Organometallic derivatives generally react with oxygen to produce complex mixtures (69,... [Pg.318]
