Abstract
Reactions of nickelocene with diphenylmethyl- and triphenylmethyllithium ha ve been studied. Several organonickel compounds were formed in these reacti ons. The products were separated by column chromatography and characterised by spectral methods. The presence of alkylated nickelocenes among products of both reactions has been confirmed. The crystal structures of two a-ally l cyclopentadienylnickel complexes have been determined by X-ray measuremen ts. Bis(eta(5)-cyclopentadieny-eta(3)-cyclopentenylnicke;) (1) crystallises in orthorhombic crystal system with eight molecules in a unit cell; space group Pbca, unit cell dimensions: a = 10.134(3), b = 11.801(3), c = 26.753( 7) Angstrom. Compound 4 contains triphenyhmethyl group eta(3)-bonded to NiC p unit. It crystallises in triclinic crystal system with four molecules in the unit cell; space group P (1) over bar; unit cell dimensions: a = 9.8747 (9), b = 10.6331(10), c = 19.569(2) Angstrom and alpha = 93.793(8), beta = 102.000(8), gamma = 113.912(7)degrees.
