| Description
| - Permethylovaný titanocen s jednou methylenovou vazbou 1 reaguje s nadbytkem interních alkinů za tvorby 1:1 produktů 3a-3c a 3f-3i vznikajících insercí trojné vazby do vazby titanu k methylenové skupině. Pouze v případě nejjednodušší molekuly 2-butinu dochází k inserci dvou molekul za vzniku známé sloučeniny 2, na druhé straně produkt inserce jedné molekuly 3j vzniká při stechiometrické reakci v poměru 1:1. 1,4-disubstituované konjugované diiny s CMe3 nebo SiMe3 substituenty reagují stejnou cestou, ale pouze jednou trojnou vazbou za vzniku sloučenin 3d a 3e. Dialkiny s dimethylsilylenovým můstkem Me2Si(C=CR)2 (R = SiMe3 nebo CMe3) poskytují reakcí obou trojných vazeb sloučeniny 3k a 3l. Po inserci první trojné vazby druhá podstupuje přesmyk, který vyústí v posunu substituentu a vzniku silacyklobutenového kruhu spojeného s atomem titanu. Alkiny nesoucí objemné substituenty CMe3 nebo SiMe3 byly nereaktivní. (cs)
- Single tucked-in permethyltitanocene 1 reacts with excess of internal alkynes to give 1:1 adducts 3a-3c and 3f-3i arising from insertion of their triple bond into the titanium-methylene bond. Only the simplest 2-butyne inserted two molecules to give the known compound 2, however, at a 1:1 stoichiometric ratio the 1:1 adduct 3j was also smoothly formed. 1,4-Disubstituted conjugated diynes with CMe3 or SiMe3 substituents reacted in the same way by only one triple bond to give 3d and 3e, respectively. The dimethylsilylene-bridged dialkynes Me2Si(C=CR)2 (R = SiMe3 or CMe3) afforded compounds 3k and 3l with both triple bonds reacting. After insertion of the first triple bond the second one underwent a rearrangement which resulted in substituent shift and formation of a silacyclobutene ring linked to the titanium atom. The alkynes bearing both bulky substituents CMe3 or SiMe3 were unreactive.
