"The singly tucked-in permethyltitanocene 1 reacts with an excess of internal alkynes to give the 1:1 adducts 3a-c,f-i, arising from insertion of the alkyne triple bond into the titanium-methylene bond. Only the simplest species, 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,e, respectively," scientists writing in the journal Organometallics report.
"The dimethylsilylene-bridged dialkynes Me2Si(C CR)(2) (R = SiMe3, CMe3) afforded compounds ...
