Isomerization of 3, 4-Dichloro-l-butene with Palladium Catalysts

Ethyl 2,6-dichloro-4-phenyl­quinoline-3-carboxyl­ate

In the title compound, C(18)H(13)Cl(2)NO(2), the quinoline ring system is almost planar (r.m.s. deviation 0.009 Å), and the phenyl and carboxyl-ate planes are twisted away from it by 59.2 (1) and 65.9 (2)°, respectively.

C 1 NQR , Crystal Structure , and Pyroelectricity of 2 , 3 - Dichloro - l , 4 - naphthoquinone *

The C1 NQR spectra of the two phases (phases I and II) of 2,3-dichloro-l,4-naphthoquinone were studied from 77 to 394 K. The crystal structure determination of the triclinic phase (phase I) was refined by single crystal X-ray diffraction. Phase I crystallizes in the space group C/-P1. The unit cell (Z = 4) has the dimensions a = 1614.3(4) pm, 6 = 828.1 (3) pm, c = 733.2(3) pm, a = 67.02(l)°, /?...

Synthesis of Supported Palladium Catalysts

The synthesis of supported palladium (Pd) catalysts is reviewed with emphasis on the chemistry of catalyst synthesis, oxidic and carbon support properties and case studies in the period 1990-2000. For the application of Pd onto oxidic supports aqueous precursor solutions are frequently used. The charge of the Pd precursor and the iso-electric point of the support are important properties since ...
