Carbonylation halides

The proton of terminal acetylenes is acidic (pKa= 25), thus they can be deprotonated to give acetylide anions which can undergo substitution reactions with alkyl halides, carbonyls, epoxides, etc. to give other acetylenes. [Pg.115]

A number of Pd or Cu catalysts bearing NHC ligands have been prepared for carbonylation of aryl halides. Nacci and co-workers synthesised the benzothiazole carbene ligated Pd complex 32 (Fig. 9.6) and tested it for aryl halide carbonylation... [Pg.226]

Sulfur compounds have also proven to be useful as nucleophilic acyl equivalents. The first reagent of this type to find general use was 1,3-dithiane, which on lithiation provides a nucleophilic acyl equivalent. The lithio derivative is a reactive nucleophile toward alkyl halides, carbonyl compounds and enones.116 117 118... [Pg.840]

The lithium derivatives described above react with electrophiles such as alkyl halides, carbonyl compounds, and thiocarbonyl compounds, resulting in the corresponding 3-substituted derivatives (190). Hydrolysis of these products by dilute acid as described in Section B,1 gives the new nonproteinogenic amino acid ester (191) along with the original amino acid ester used as the chiral auxiliary. The chemical yields are above 80% (83MI1). [Pg.260]

Substituted cyclobutenes 2-substituted 1,3-dienes. The reagent reacts with various electrophiles (alkyl halides, carbonyl compounds, epoxides) to give the corresponding selenides, jS-hydroxy- and y-hydroxyselenides, respectively. Three methods can be used to convert these adducts to cyclobutenes, as shown in equations... [Pg.233]

Highly fluorinated ethenes react readily with oxygen to yield epoxides, polymeric peroxides, perfluorocyclopropane, and, by rearrangement, fluorinated acetyl halides carbonyl fluoride and carbon dioxide are undesired byproducts, the amount of which is dependent on the method used. [Pg.8]

Finally, it should be mentioned that there is one important commercial application of the organic halide carbonylation. This is in the rhodium and methyl iodide-catalyzed conversion of methanol and carbon monoxide into acetic acid (25). The mechanism of the reaction appears to involve the oxidative addition of methyl iodide to the rhodium(I) catalyst followed by CO insertion and hydrolysis ... [Pg.335]

A list of the reported ionic heptacoordinate halide carbonyl cations and related complexes is presented in Table I. [Pg.134]
