Belsky et al., Dimerization of cyclopentadienyl ligands in the synthesis of transition metal complexes. 1,4,5,6,7,10,11,12-octamethyltricyclo[7.3.0.0(3,7)]-dodeca-3,5,9,11-tetraene and the complex of 1,1 ',3,3 '-tetrakis-(tert-butyl)-1,1 '-dihydrofulvalene with I-3(-), RUSS CHEM B, 48(12), 1999, pp. 2285-2289
1,4,5,6,7,10,11,12-Octamethyltricyclo[7.3.0.0(3,7)]dodeca-3,5,9,11-tetraene
was obtained as a by-product in the synthesis of (C5Me5)(2)CeCl from CeCl3
and NaC5Me5. The complex of 1,1',3,3'-tetrakis(tert-butyl)-1,1'-dihydroful
valene with I-3(-) was obtained as the major product in the reaction of YbI
3 with 1,3-(Bu2C5H3Na)-C-t. The structures of the title compounds were esta
blished by X-ray diffraction analysis.
