摘要：
Recent accomplishments in the cyclopolymerization of ,-diynes by tailored Ru- and Mo-alkylidenes are reported. Special emphasis is put on the extent and origin of both stereo- and regioselectivity with the different initiator systems used. Particularly, the very recently developed molybdenum imido alkylidene N-heterocyclic carbene (NHC) complexes are of utmost interest since they allow for the cyclopolymerization of ,-diynes bearing protic functional groups such as hydroxyls and carboxylic acids and therefore rival Ru-alkylidenes both in terms of regio- and stereoselectivity but also in terms of activity and functional group tolerance.
