Abstract: Abstract A series of germinal-diethynylethene (gem-DEE) bridged diferrocenyl compounds, including 1,1-[bis(ferrocenylethynyl)methylene]cyclohexane (1), 1,1-[bis(ferrocenylethynyl)methylene]tetrahydro-2H-pyran (2), and 1,1-[bis(ferrocenylethynyl)methylene]tetrahydro-2H-thiopyran (3) were synthesized and characterized. The Fe⋯Fe distance between the two ferrocenyl termini reaches up to ∼9 A for compounds… read more here.
