Synthesis and Anti-HIV-1 Evaluation of New Sonogashira-Modified Emivirine (MKC-442) Analogues was written by Danel, Krzysztof;Joergensen, Per T.;Pedersen, Erik B.;La Colla, Paolo;Collu, Gabriella;Loddo, Roberta. And the article was included in Helvetica Chimica Acta in 2009.Name: 2-(Chloromethyl)-1,3-difluorobenzene This article mentions the following:

The MKC-442 analog 6-(3,5-dimethylbenzyl)-5-ethyluracil substituted with a (propargyloxy)methyl group at N(1) has previously been found highly active against HIV-1. The CC bond in the substituent at N(1) is here utilized in a series of chem. reactions in order to develop new agents with higher activity against HIV-1-resistant mutants. The syntheses involved Pd-catalyzed C,C-coupling reactions, addition of disulfides, and click chem. on the terminal CC bond as well as addition of bromine to the so formed internal CC bonds. Sonogashira couplings were performed with silyl-derivatized iodobenzyl alcs. which, after deprotection, were oxidized to aldehydes by means of IBX. The isomeric alc. I was obtained in the Sonogashira reaction of propargyl alc. with the N(1)-substituted (4-iodobenzyloxy)methyl derivative of the above mentioned uracil. Compound I turned out to be the most effective compound against problematic HIV-1 mutants. The general observation in the present work is that a combination of alkyne and aryl in the substituent at N(1) leads to highly active compounds against HIV-1. In the experiment, the researchers used many compounds, for example, 2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4Name: 2-(Chloromethyl)-1,3-difluorobenzene).

2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Name: 2-(Chloromethyl)-1,3-difluorobenzene

Determination of positional weighting factors for the Swain and Lupton substituent constants f and r was written by Williams, S. G.;Norrington, F. E.. And the article was included in Journal of the American Chemical Society in 1976.Product Details of 5344-49-0 This article mentions the following:

Addnl. data considered in abstracting and indexing are available from a source cited in the original document. Previous workers (Swain, C. G. and Lupton, E. C., 1968) have shown that Hammett’s substituent constant σ and related parameters can all be expressed as a linear combination of two principal components F and R, which represent resp. the field and resonance effects of the substituent without regard for its position in the mol. A statistical anal. of data from 45 reaction series was carried out to determine positional weighting factors f and r for F and R, to enable the latter to be applied to the ortho, meta, and para positions of a benzene ring simultaneously. The fpara and rpara were both defined as 1.000. Fmeta was 0.980 (not significantly different from 1.000), fortho 1.248, rmeta 0.347, and rortho 0.863. These values agree roughly with the ad hoc assumptions made hitherto by classical organic chemists and enable good correlations to be found between physicochem. properties of the side chain and substituent parameters of mixed or multiply substituted populations of benzenoid compounds They also demonstrate that generalized σ-type parameters may be successfully applied to the ortho position, although the correlation with observed data is less good than with the meta and para positions due, no doubt, to the proximity of the substituent to the side chain of the mol. In the experiment, the researchers used many compounds, for example, 2-Chloro-6-nitrobenzoic acid (cas: 5344-49-0Product Details of 5344-49-0).

In palladium/norbornene (Pd/NBE) chem., the “ortho effect” has been proven to be a key factor in the process of β-carbon elimination to extrude NBE.
