Vn. Postnov et al., THE BEHAVIOR OF 2-METHYLENE-3-FERROCENYLMETHYLENECAMPHANE UNDER CONDITIONS LEADING TO THE CYCLODIMERIZATION OF FERROCENYL-1,3-BUTADIENES, Journal of organometallic chemistry, 476(2), 1994, pp. 189-195
The behaviour of 2-methylene-3-ferrocenylmethylenecamphane under proto
n cyclodimerization conditions has been investigated. The stage involv
ing the formation of the dimeric linear allylic cation has been confir
med in these interactions by isolating of corresponding diene. Its str
ucture has been established unambiguously by X-ray methods. All substa
nces isolated have been characterized by elemental analyses and H-1 an
d C-13 NMR spectral data. .
