1-(1-Bromo-2,2-diphenylvinyl)-4-ethylbenzene, CCc1ccc(cc1)C(=C(c2ccccc2)c3ccccc3)Br It is always difficult to initiate Grignard reaction with chloro substrates.

To this a small amount of iodine (~ 0.5-1 g) and ethyl bromide (2-3 mL, one can also use di-bromoethane) added without stirring and observed for initiation of the reaction.

CopyCopied, CSID:28313, http://www.chemspider.com/Chemical-Structure.28313.html (accessed 18:53, Nov 13, 2020) The reaction of 1,4‐di‐tert.butylbenzene in carbon tetrachloride with bromine and with iron as catalyst yields 1,4‐di‐tert.butyl‐2‐bromobenzene, 1‐tert.butyl‐3‐bromobenzene, 1‐tert.butyl‐4‐bromobenzene, and 1‐tert.butyl‐3,4 CopyCopied, MKBOLRVWSAJJIK-UHFFFAOYSA-N 16.7), the carbocation can form bromobenzene, a stable aro-matic compound. THF can be dried with KOH, just before the reaction. Ethylbenzene to benzene organic conversion is a two step process.

130, 1322 (1900); D. A. Shirley, Org. This page only looks at the ways of making the aryl halides, chlorobenzene, bromobenzene and iodobenzene, as required by some UK A level syllabuses. Empirical Formula (Hill Notation) C 6 H 5 Br . First ethylbenzene reacts with acidic potassium permanganate to give benzoic acid. Once the initiation starts continue the addition of mixture of chlorobenzene and bromobenzene over period of 1 hr keeping the exothermic reaction. Add water (200 mL) and separate water layer. The THF thus obtained is decanted to the reaction flask.
