Metal reaction with organometallic

Brief consideration will be given to NMR investigation of intermediates, products and kinetics of reactions. Alkylation, arylation, metalation, reaction with organometallics, thermolysis and thermal rearrangements, isomerisation and many other reactions such as the Wittig, Michaelis and Arbuzov reactions, which are typical of organophosphorus... [Pg.85]

Isocyanates can be used as the source of the N(3)-C(4) unit by reaction with organometallic intermediates. For example, the reaction of ethyl 2-(bromophenyl)imidates 875 with lithium metal, followed by quenching of the lithiated intermediate 876 with phenyl isothiocyanate gave 3-phenyl-2-substituted 4(3//)-quinazolinethiones 877 <1996SC3167>. [Pg.218]

In the reactions with organometallic complexes of f-metals, the reactivity of a pure Lewis base for the 1,3,2(A2)-diazasiloles was observed. Thus, silylene 85 reacts with (Cp)3Ln to give the complexes (Cp)3Ln(85) (Ln = Y, Yb)... [Pg.676]

The effects of metal-containing POSS on the combustion behavior of polypropylene have been investigated.46 Metal-POSS was prepared from incompletely condensed structures by reaction with organometallic compounds. The dimeric and oligomeric of Al and Zn-isobutyl silsesquiox-ane (POSS) have been evaluated as potential flame retardants for polypropylene, and the results were compared with PP/octaisobutyl POSS. The cone calorimeter data (Table 8.2) revealed that... [Pg.194]

To show how these general principles of nucleophilic substitution and addition apply to carbonyl compounds, we are going to discuss oxidation and reduction reactions, and reactions with organometallic reagents—compounds that contain carbon-metal bonds. We begin with reduction to build on what you learned previously in Chapter 12. [Pg.727]

Aprotic solvent. The use of this solvent for reactions with organometallic compounds has been reviewed by Agami.3 The diamine is comparable to mono-glyme (CH3OCH2CH2OCH3) in its ability to form complexes with organo-metallics. [Pg.348]

Two available examples are nucleophilic reactions with organometallic cations and with activated bicyclobutanes. Sweigart and co-workers (9, 10) showed that a linear correlation is obtained between the log k values for the reactions of nucleophiles (Nu) with various organic cations and the transition metal complexes of the same cations. The latter reactions resemble SN2 reactions if the carbon-metal bond cleavage is considered as a departure of the leaving group ... [Pg.179]

Acid chlorides are prepared by standard methods and undergo the usual acid chloride reactions. They have found important applications as substrates in the syntheses of ketones by transition metal-catalyzed coupling reactions with organometallics (Section 6.02.5.5.14). Acid chlorides (424) are also good substrates for the preparation of ketones (425) using organomanganese(II) iodide, especially for the preparation of alkyl pyrimidinyl ketones <86ACS(B)764>. [Pg.183]

Reactions of Transition Metal Compounds with Organometallic... [Pg.41]

OrganometaUic complexes are usually assumed to be rather unstable, for instance with respect to high temperatures. It is an interesting fact that organometallic-catalyzed reactions are successfully carried out in SCW. The advantage of organo-metallic reactions with respect to their technical application can be the facile separation of products upon cooling. [Pg.431]
