Nucleophilic deoxyfluorinalton of one of the two hydroxyl groups of catechols has been developed via the Umpolung concept. This method was successively applied to naturally occurring catechols, such as catechins and dopamine, to produce novel fluorinated analogues.

A series of soluble α-diimine late transition metal catalysts has been invented comprising a substituted or unsubstituted catecholate ligand. The catalysts demonstrate high activity and selectivity for linear α-olefins. As such, these catalysts conveniently oligomerize ethylene. Typical activators as known to those of ordinary skill in the art are used to activate these transition metal catalysts. These catalysts can be used in a supported or unsupported form.
