Eisch**, Xian Shi, Jacek Lasota Department of Chemistry, The State University of New York at Binghamton, Binghamton, New York 13902-6000, U.S.A. Dedicated to Professor Dr. Dr. h. c. mult. Günther Wilke on the occasion of his 70th birthday Z. Naturforsch. 50b, 342-350 (1995), received September 20, 1994 Carbon-Carbon Bond Formation, Reductive Coupling, Titanium(II) Chloride, Oxidative Addition, Carbonyl and Benzylic Halide Substrates Titanium(II) bis(tetrahydrofuran) 1, generated by the treatment of TiCl4 in THF with two equivalents of n-butyllithium at -78 °C, has been found to form carbon-carbon bonds with a variety of organic substrates by reductive coupling. Diphenylacetylene is dimerized to ex clusively (E,E)-1,2,3,4-tetraphenyl-l,3-butadiene; benzyl bromide and 9-bromofluorene give their coupled products, bibenzyl and 9,9'-bifluorenyl, as do benzal chloride and benzotrichlo- ride yield the l,2-dichloro-l,2-diphenylethanes and l,l,2,2-tetrachloro-l,2-diphenylethane, respectively. Styrene oxide and and ris-stilbene oxide undergo deoxygenation to styrene and fra/«-stilbene, while benzyl alcohol and benzopinacol are coupled to bibenzyl and to a mix ture of tetraphenylethylene and 1,1,2,2-tetraphenylethane. Both aliphatic and aromatic ke tones are smoothly reductively coupled to a mixture of pinacols and/or olefins in varying proportions. By a choice of experimental conditions either the pinacol or the olefin could be made the predominant product in certain cases. The reaction has been carried out with heptanal, cyclohexanone, benzonitrile, benzaldehyde, furfural, acetophenone, benzophenone and 9-fluorenone. -

Screening Assessment for the Challenge Benzene, (chloromethyl)- (Benzyl chloride) Chemical Abstracts Service Registry Number 100-44-7 Environment Canada Health Canada November 2009 Screening Assessment CAS RN 100-44-7 Synopsis Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment of benzene, (chloromethyl)-, also known as benzyl chloride, Chemical Abstracts Service Registry Number 100-44-7. This substance was identified in the categorization of the Domestic Substances List (DSL) as a high priority for action under the Challenge. Benzyl chloride was identified as presenting greatest potential for exposure of individuals in Canada and had been classified by other agencies on the basis of carcinogenicity and genotoxicity. Although the substance met the categorization criteria for persistence, it did not meet the criteria for bioaccumulation potential or inherent toxicity to aquatic organisms; therefore, the focus of this assessment relates primarily to human health aspects. According to data submitted in response to a Notice issued under section 71 of the Act, no persons in Canada reported manufacturing benzyl chloride in a quantity greater than or equal to the reporting threshold of 100 kg for the 2006 calendar year. However, it was reported that 100 000–1 000 000 kg were imported into Canada in that year. The response to the section 71 notice indicated that benzyl chloride is mainly used in Canada as a chemical intermediate for the synthesis of quaternary ammonium compounds, which are used primarily as hard surface sanitizers, corrosion inhibitors, fungicides in industrial cleaners and bactericides in surfactants in household and personal care products.
