Sv. Timofeev et al., Electrophilic substitution reactions of ferracarborane 3-(eta(5)-Cp)-4-SMe2-3,1,2-FeC2B9H10, RUSS CHEM B, 49(9), 2000, pp. 1598-1604
Mercuration and bromination reactions of ferracarborane 3-(eta (5)-Cp)-4-SM
e2-3,1,2-FeC2B9H10 (1) were investigated. Mercuration of 1 under mild condi
tions (mercury trifluoroacetate in dichloromethane) results in 8-monosubsti
tuted mercury derivative as the only reaction product. Depending on the rea
ction conditions, bromination of 1 results in 8-mono- or 7,8-disubstituted
bromo derivatives. The structures of the monomercury and dibromo derivative
s of 1 were established by X-ray analysis.
