The degradation of organophosphorous nerve agents is of primary concern due to the severe toxicity of these agents. Based on the active center of organophosphorus hydrolase (OPH), a bimetallic nuclear ligand, (5-vinyl-1,3-phenylene)bis(di(1H-imidazol-2-yl) methanol) (VPIM), was designed and synthesized, which contains

Potassium trifluoroborates are a special class of organoboron reagents that offer several advantages over the corresponding boronic acids and esters in that they are moisture- and air-stable, and are remarkably compliant with strong oxidative conditions.

These bench stable Potassium Organotrifluoroborates are useful for Suzuki-Miyaura cross-coupling reactions and have also been used for a variety of other C-C bond forming reactions. Importantly, these reagents are compatible with a wide range of functional groups and are stable to many commonly used and harsh reaction conditions.
