Abstract

original image

A diverse array of nitrogen-containing compounds were formed by the addition of hydrazine to alkynes, diynes, enynes, and allenes in the presence of cationic gold(I) complexes with a cyclic (alkyl)(amino)carbene ligand (see scheme; the X-ray crystal structure of the gold–hydrazine complex is shown). This hydroamination is an ideal initial step for the preparation of acyclic and heterocyclic bulk chemicals. Dipp=2,6-diisopropylphenyl.
