Organometallic Nickel NCN Pincer Complex Promotes L-Lactate Racemization in Water

The air-stable and water-soluble salt [(NCNMe+)Ni(NCCH3)](OTf)2 (NCNMe+= 3,5-bis(4,4-dimethyl-4,5-dihydrooxazol-2-yl)-1,2,6-trimethylpyridin-1-ium) was synthesized and characterized. As a partial structural mimic, [(NCNMe+)Ni(NCCH3)]2+ retains the unusual 4-pyridylidene-based pincer framework present in the nickel pincer nucleotide...
