Abstrakt: Addition of NaEt 3 BH to ( Ph2PPr DI)CoCl 2 affords the corresponding monohydride, ( Ph2PPr DI)CoH. X-ray diffraction and DFT calculations indicate that this compound possesses a radical monoanion α-DI chelate and a Co(ii) centre. Notably, ( Ph2PPr DI)CoH catalyzes the hydroboration of alkynes and dihydroboration of nitriles under mild conditions.
