Description
| - Komplexy [Zr(?2-Me3SiCCSiMe3)(?5-C5Me4R)2], kde R = Me (5), H (6), a SiMe3 (7), reagují s terminálními acetyleny HCCR' (R' = CMe3, SiMe3, ferocenyl (Fc), a Ph) na alkenyl-alkinylové komplexy [Zr(?1-CCR'){?3-C(SiMe3)=CH(SiMe3)}(?5-C5Me4R)2], R/R' = Me/CMe3 (5a), Me/SiMe3 (5b); H/CMe3 (6a), H/SiMe3 (6b), H/Fc (6c), H/Ph (6d); SiMe3/CMe3 (7a), a SiMe3/Fc (7c). Komplex 7a vzniklý in situ z 7 and HCCCMe3 dimerizuje t-butylacetylen výhradně na hlava-k-patě dimer Me3C(=CH2)CC?CCMe3 a po spotřebování veškerého terminálního acetylenu je obnoven původní komplex 7. Komplex 7 reaguje podobně s 1-hexinem, fenylethinem a (trimethylsilyl)ethinem, za vzniku alkenyl-alkinylových komplexů, které rovněž podléhají zpětné reakci na původní komplex 7 po odpaření kapalných složek, avšak u těchto terminálních acetylenů nebyla pozorována dimerizace žádným komplexem 5-7.

- Complexes [Zr(?2-Me3SiC/CSiMe3)(?5-C5Me4R)2], where R = Me (5), H (6), and SiMe3 (7), reacted smoothly with terminal alkynes HC/CR'' (R'' = CMe3, SiMe3, ferrocenyl (Fc), and Ph) to give agostic alkenyl-alkynyl complexes [Zr(?1-C/CR''){?3-C(SiMe3)=CH(SiMe3)}(?5-C5Me4R)2], R/R'' = Me/CMe3 (5a), Me/SiMe3 (5b); H/CMe3 (6a), H/SiMe3 (6b), H/Fc (6c), H/Ph (6d); SiMe3/CMe3 (7a), and SiMe3/Fc (7c). Complex 7a formed from 7 and HC/CCMe3 dimerized t-butylethyne to give pure head-to-tail dimer Me3C(=CH2)CC/CCMe3 until all the alkyne was consumed and then it restored complex 7. Complex 7 reacted with 1-hexyne, phenylethyne and (trimethylsilyl)ethyne to give alkenyl-alkynyl complexes; however, evaporation of the alkynes in vacuum restored 7, and neither of these alkynes dimerized.
