Rearrangement under control: A wide variety of 3,4,5- and 1,3,5-trisubstituted pyrazoles can be prepared from tosylhydrazones of ketones and terminal alkynes through the title reaction sequence (see scheme; Ts=4-toluenesulfonyl). The rearrangement, and th

Gold-catalyzed hydroamination of alkynes and allenes with parent hydrazine

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. Copyright
