Imidoosmium complex

Treatment of [(arene)OsCl2]2 with lithium amide in THF results in the formation of imidoosmium complexes in high yield, which react with a with wide variety of active hydrogen compounds and polar compounds (Scheme 10.28) [253]. 

Most transition metal imido (nitrene) complexes are nucleophilic at nitrogen, but certain species exhibit electrophilic character. Procedures for the catalytic oxyamination and aziridination of alkenes have been developed where imidoosmium and manganese species, respectively, are generated in situ. 

Treatment of dialkoxoosmium(II) shown in Scheme 3.93 with BuNH2 results in the successive N-H bond cleavages to give imidoosmium(II) complex...
