摘要:
A metastable solution of GaCl reacts with LiCp or MgCp(2) compounds to a number of new cyclopentadienylgallium(I) species: GaCp*, GaCp(tBu), GaCp((SiMe3)3) and GaCp((Benzyl)5). They are characterized by their mass and NMR spectra (H-1, C-13 and Ga-71). By comparison with analogous Al and Mg compounds eta(5)-bonding has to be concluded for air GaCp derivatives.
