REACTIONS OF FERROCENE AND NICKELOCENE WITH SOME STABLE CARBONIUM-IONS

The reaction of ferrocene and tropylium hexafluorophosphate yields ferrocenyltropylium PF6, which crystallizes in the monoclinic space group P2(1)/C (a = 9.7858(10) angstrom, b = 16.3692(24) angstrom, c = 10.901(4) angstrom, beta = 113.030(18)-degrees, Z = 4, T = 27-degrees-C, V = 1607.0(7) angstrom3, R(f) = 0.091, R(w) = 0.040) for 102 parameters and 929 observed (I > 2.5 sigma(I)) out of 2087 total measured reflections. The reaction of nickelocene and triphenylmethyl tetrafluoroborate yields triphenylmethylcyclopentenyl cyclopentadienyl nickel tetrafluoroborate, which crystallizes in the monoclinic space group P2(1)/n (a = 11.0306(19) angstrom, b = 14.078(4) antgstrom, c = 17.117(4) angstrom, beta = 101. 134(18)-degrees, Z = 4, T = 27-degrees-C, V = 2608.0(11) angstrom3, R(f) = 0.091, R(w) = 0.035) for 147 parameters and 1334 out of 3361 measured reflections.
