Article abstract of DOI:10.1016/0022-328X(90)87262-C

Treatment of cis- with Me2NNH2 in hot benzene gives the title compound (1a) in high yield.Similar treatment of , X = Br or I, gives the corresponding bromo- or iodo-complexes X, X = Br or I. 1a with NH4PF6 gives the corresponding PF6 salt , which with dilute HCl and NH4PF6 gives 2.Treatment of 1a with NaBH4 gives a neutral hydrido complex, formulated as .The crystal structure of 1a has been determined.NMR data are given.
