Khaskin, Eugene published the artcileFormal loss of an H radical by a cobalt complex via metal-ligand cooperation, SDS of cas: 338800-13-8, the publication is Chemical Communications (Cambridge, United Kingdom) (2013), 49(27), 2771-2773, database is CAplus and MEDLINE.
A (PNP)Co(i)methyl diamagnetic complex formally loses an H atom from the pincer ligand, exhibiting a long-range metal-ligand cooperation in what may be considered as an unusual example of C-H cleavage. Spectroscopic data indicate that the product is a neutral Co(i) complex with a radical delocalized in the ligand backbone.
Chemical Communications (Cambridge, United Kingdom) published new progress about 338800-13-8. 338800-13-8 belongs to pyridine-derivatives, auxiliary class Bis-phosphine Ligands, name is 2,6-Bis((di-tert-butylphosphino)methyl)pyridine, and the molecular formula is C23H43NP2, SDS of cas: 338800-13-8.
