Solvolysis of 2-substituted-9-(ortho-substituted phenylmethyl)fluoren-9-yltrimethylammonium ions in various solvents. The effect of steric crowding on alkene formation was written by Smith, Peter James;Pradhan, Jyotsna. And the article was included in Canadian Journal of Chemistry in 1986.Application of 83902-02-7 This article mentions the following:
The solvolytic reaction of several 9-(o-substituted phenylmethyl)fluoren-9-yltrimethylammonium salts has been investigated in several different solvents. Substitution and elimination products were found for the reactions in all the solvents studied, with the exceptions that reaction in both tert-Bu alc. and chloroform led exclusively to the alkene product. The observed rate constants for alkene formation and the percent alkene were measured and it was found that the di-o compounds reacted at a faster rate but produced less alkene than the reaction of the corresponding mono-o salts. Hydrogen-deuterium isotope effects were also determined for the various reactions. The results are discussed in terms of the reaction proceeding by way of the E1 mechanism, where steric acceleration promotes the loss of the bulky ammonium leaving group to give the carbocation intermediate. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7Application of 83902-02-7).
2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Application of 83902-02-7
