Abstract

Solid GaI reacts with NaCp to yield (eta(5)-cyclopentadienyl)gallium (GaCp) (1). During the synthesis the side product, CpGa -> GaCp(2)I (2), with a rare gallium-gallium donor-acceptor bond could be isolated. The reaction of 1 with B(C(6)F(5))(3) affords CpGa -> B(C(6)F(5))(3) (4). The molecular structures of 2 and 4, which contain the first GaCp moieties, are presented. The convenient synthesis of 1 needs only standard laboratory equipment and certainly opens the door for 1 to become a versatile reagent in organometallic chemistry; awakening the sleeping beauty GaCp nearly twenty years after its initial discovery.
