Page/Page column, (2013/03/26)
The present invention generally relates to a process that selectively polymerizes ethylene in the presence of an alpha-olefin, and to a metal-ligand complex (precatalyst) and catalyst useful in such processes, and to related compositions. The present invention also generally relates to ligands and intermediates useful for preparing the metal-ligand complex and to processes of their preparation.

4-Bromo- and 4-Chloro-3-butylphenol, two potent fungistatics, were prepared in an efficient 3-step synthesis from commercially available materials.Crucial to the synthesis is the use of halo-substituents as positional protective groups.
