DESCRIPTION:Homogeneous gold catalysis is now recognized as a “convenient t
 ool for generating molecular complexity” [1] and diversity. [2] The major 
 part of the synthetic chemistry which has been developed so far in this fi
 eld is intimately linked to the p Lewis acidic property of cationic gold(I
 ) and gold(III) species.[3] The latter have indeed proven to be particular
 ly useful catalysts for the functionalization of p systems such as alkynes
  or allenes by addition of various oxygen\, nitrogen and carbon nucleophil
 es. In addition to its acidic character\, gold can potentially act as an e
 lectron donor thus allowing the stabilization of intermediate cationic spe
 cies and favoring reaction pathways not accessible with other Lewis acids.
 \n\nDuring the past six years\, we have been actively involved in this dom
 ain and have developed a series of new methods allowing the formation of v
 arious hetero- and carbocyclic systems by taking advantage of the singular
  reactivity of cationic gold species. This lecture will highlight some of 
 our contributions to the field including hydride\, nitrene\, and oxene tra
 nsfers onto alkynes and allenes.[4]\n\n[1] Fürstner\, A. Chem. Soc. Rev. 2
