Most 1-bromoalkanes are prepared by free-radical addition of hydrogen bromide to the 1-alkene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo derivative. [2] 1-Bromohexane undergoes reactions expected of simple alkyl bromides. It can form Grignard reagents. [3]
A mixture of cis-decalin and CXB can simultaneously match optical index and density of PMMA. [1] Due to the moderate dielectric constant of CXB (ε = 7.9 [ 2 ] ), PMMA acquires charges that can be screened by the addition of salt (e.g. tetrabutyl ammonium bromide ), leading to a very good approximation of colloidal hard sphere .

Retrosynthetic analysis was used as early as 1917 in Robinson's Tropinone total synthesis. [1] Important conceptual work on retrosynthetic analysis was published by George Vladutz in 1963 . [ 2 ] [ 3 ] E.J. Corey formalized and popularized the concept from 1967 onwards in his article General methods for the construction of complex molecules and ...
