ArAR

It has also proved possible to close larger rings in this manner 8 and even 12-membered. Triarylamines have been prepared in a similar manner from Arl and Ar NLi, even with unactivated Arl. In the Goldberg reaction, an aryl bromide reacts with an acetanilide in the presence of K2CO3 and Cul to give an N-acetyl-diarylamine, which can be hydrolyzed to a diarylamine ArBr-I- Ar NHAc—> ArAr NAc. ... [Pg.864]

Organocopper compounds have been trapped by coordination with organic bases. In addition, arylcopper compounds (ArCu) have been independently prepared and shown to give biaryls (ArAr ) when treated with aryl iodides (Ar I). A similar reaction has been used for ring closure. [Pg.871]

In another nonelectrolytic process, arylacetic acids are converted to vi c-diaryl compounds 2A1CR2COOH —> ArCR2CR2Ar by treatment with sodium persulfate (Na2S20g) and a catalytic amount of AgNOs." Both of these reactions involve dimerization of free radicals. In still another process, electron-deficient aromatic acyl chlorides are dimerized to biaryls (2 ArCOCl —> ArAr) by treatment with a disilane RsSiSiRs and a palladium catalyst." " ... [Pg.942]

Beginning preliminary identification of ARARs and to be considered (TBC) information. This preliminarily identifies the ARARs that are expected to apply to site characterization and site remediation activities. [Pg.594]

During site characterization, communication is required between the lead and support agencies. The information is mainly on identifying ARARs, and includes a description of the contaminants of concern, the affected media, and any physical features. This information may be supplied by the preliminary site characterization summary or by a letter or other document. [Pg.602]

Developing remedial action objectives specifying the contaminant and media of interest, exposure pathways, and preliminarily remediation goals that permit a range of treatment and containment alternatives to be developed on the basis of chemical-specific ARARs when available, other available information, and site-specific, risk-... [Pg.604]

Compliance with ARARs. It is considered how each alternative will comply with ARARs, or if a waiver is required and how it is justified. [Pg.605]

The evaluation of the ability of the alternatives to comply with ARARs includes a review of chemical-specific and action-specific ARARs as listed in Table 16.10. All alternatives will meet all of their respective ARARs except the nonaction alternative. [Pg.649]
