We have focused our attention on cycloisomerization reactions involving silver‐ and gold‐based homogeneous catalysis. This topic is divided into two parts: one relating to cycloisomerization with an allene group and the other with an alkyne group. In each case we have then studied different partners such as carbonyl/carboxy groups, imines, amides or alkenes. Reactions involving allene and alkyne systems as partners are also briefly reported, along with miscellaneous transformations. Our purpose is also to stimulate some discussion by setting together the contributions of differentauthors to each type of cycloisomerization reaction. Meanwhile, we have outlined when necessary the impact of the choice of counterion or metal (silver vs. gold) in the course of the reaction. Finally, some mechanistic discussion and reaction intermediates are also mentioned if available.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
