Benzenediamine (185) and benzoin (186) gave a separable mixture of 2,3-diphenyl-1,2-dihydroquinoxaline (187, R = Ph) and 2,3-diphenylquinoxaline (188, R = Ph) (dry mixture, microwave irradiation under reflux, 4 min 21% and 67%, respectively) in contrast, similar treatment with m,m -dichloro-benzoin gave only the aromatized product, 2,3-bis(m-chlorophenyl)quinoxa-line (188, R = C6H4Cl-m) (94%). ... 

The versatile starting material lCp RuCI 4 (1) reacts rapidly with sterically demanding phosphines (PCy and P Pr ) as well as with the nucleophilic carbene ligands (L) to give deep blue, coordinatively unsaturated Cp Ru(L)CI complexes 2-8 (L= l,.Tbis(2,4,6-lrimethylphenyl) (IMes. 2) 1,3-R2-imidazol-2-ylidene = cyclohcxyl (ICy, 3) 4-methylphenyl (ITol, 4) 4-chlorophenyl (IPCl, 5) adamanlyl (lAd, 6) 4..5-dichloro-1,3-bis(2.4,6-trimethylphenyl) (IMesCI, 7) and 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidenc (IPr. 8) in high yields according to Eq. (4).

The relevance of the palladium-catalyzed amidocarbonylation for natural product synthesis has been demonstrated with the multi gram-scale preparation of the central amino acid of chloropeptin I ((S)-3,5-dichloro-4-hydroxyphenylglycine) as well as methionine and p-chlorophenyl alanine via the combination of amidocarbonylation and enzymatic hydrolysis (Table 4) [44]. 

More general cases are encountered in the metabolism of a variety of ha-log enated hydrocarbon solvents and insecticides [58]. Examples include the dehydrochlorination of 1,1,2,2-tetrachloroethane to trichloroethylene in the mouse, and of DDT (l,l,l-trichloro-2,2-bis(4-chlorophenyl)ethane) to DDE (l,l-dichloro-2,2-bis(4-chlorophenyl)ethene) [58][77]. Glutathione transferases may be involved in some of these reactions. 

Photolytic. When an aqueous solution of p,//-DDE (0.004 pM) in natural water samples from California and Hawaii were irradiated (maximum X = 240 nm) for 120 h, 62% was photooxidized to jD,p -dichlorobenzophenone (Ross and Crosby, 1985). In an air-saturated distilled water medium irradiated with monochromic light (>. = 313 nm), p,//-DDE degraded to jo,//-dichloro-benzophenone, l,l-bis(p-chlorophenyl)-2-chloroethylene (DDMU), and l-(4-chlorophenyl)-l-(2,4-dichlorophenyl)-2-chloroethylene (o-chloro DDMU). Identical photoproducts were also observed using tap water containing Mississippi River sediments (Miller and Zepp, 1979). The photolysis half-life under sunlight irradiation was reported to be 1.5 d (Mansour et al., 1989).
