Vicinal Diamination of Terminal Olefins

The present publication describes an efficient and mild three-step conversion of a terminal olefin 1 into the corresponding 1,2-diamine 5. The sequence includes: azidoiodination, substitution with NaN3, and catalytic hydrogenolysis. The terminal 1,2-diamine 5 was converted into its cis-dichloroplatinum(II) complex 6.
