Palladium, dichlorobis

A degassed suspension of lhe halo compound 14 and an alkyne (1.2 equiv) in Et3N (0.1-0.2 mol) was stirred in the presence of dichlorobis(triphenylphosphane)palladium(II) (0.02 equiv) and coppcr(I) iodide (0.04 equiv) at 20 C for 20 h. EtOAc was added and the mixture was washed with H20 and brine the organic phase was dried (MgSOi) and evaporated to yield the product. [Pg.412]

Bidentate roles are ascribed to the thianthrene in the yellow dichlo-robis(thianthrene)palladium(II) and dichlorobis(thianthrene)platinum(II) solids formed in high yields by reaction of thianthrene in ethanol with... [Pg.362]

Treatment of 1-azirine (292) with catalytic quantities of dichlorobis(benzonitrile)pal-ladium(II) gave a quantitative yield of the indole (293) (77CC664). This transformation proceeds through the intermediacy of a 2 1 azirine-palladium chloride complex. Conversion of the 1-azirine ring to indoles under uncatalyzed thermolytic conditions provides a mechanistically interesting comparison with the Pd(II)-catalyzed conversions. The C—N bond cleavage in the latter is apparently accelerated as a result of the coordination of the azirine to palladium. [Pg.76]

The modified Suzuki polymerization catalyst, dichlorobis(tri-o-tolylphosphine) palladium(II), was also used to prepare poly(2,7-(9,9-di-w-octylfluoiene)-3,6-benzothiadiazole), (I). [Pg.367]

Selective transfer of the homoenolate moiety characterizes the transmetalation from tin to titanium described in the previous section. A very facile transmetalation of the same kind occurs for 3-stannylketoxime, Eq. (50) [48]. Reaction of the ( )- 3-(tributyltin)ketoxime with dichlorobis(benzonitrile)palladium in CH2C12 at 0 °C for 30 min yields 78% of the transmetalation product. The... [Pg.24]

Lactone synthesis.2 Carbonylation of simple organic halides can be carried out readily with several palladium catalysts such as bis(diphenylphosphinoethane)-his(triphenylphosphine)palladium(0) and dichlorobis(triphenylphosphinc)pal-ludium(ll). The latter catalyst is preferred because it is stable and easily converted to Pd(0) in situ. Carbonylation of halo alcohols provides a useful synthesis of various lactones. [Pg.133]

The facts that the phenylacetyl complex Villa also undergoes a reaction with phenylacetyl chloride under identical experimental conditions to yield dibenzyl ketone, XVIII (218% with respect to Villa), and that XVII was also obtained from the reaction of phenylacetyl chloride with dichlorobis(triphenylphosphine)palladium(0), XIX, implicate XIX in the catalytic cycle. The palladium (II) complex XIX does indeed catalyze the conversion of an acyl halide to the corresponding symmetrical ketone (123% with respect to XIX). The palladium (IV) structures are only... [Pg.112]

In the presence of Pd(II) catalysts, 1 couples with aryl or vinyl iodides. For the former coupling, the most satisfactory catalyst is dichlorobis(tri-o-tolylphos-phine)palladium(II). Pd[P(C6H5)3]4 is satisfactory for coupling with vinyl iodides or triflates.2... [Pg.220]
