The syntheses of the new compounds [η-C5H5)2H2], where R = (C6F5) 1, Ph 2, H 3 or Cl 4, [Mo(η-C5H5)2H2] 5, [Mo(n-C5H5)2(H)(n'-H2B(C6F5)2)] 6, [Mo(η-C5H5)2H2)] 7, [Re(η-C5H5)2H2]-0.5C 6H5Me 8, [Ta(η-C5H5)2H2] 9 and [Re(n-C5H5)(r,-C5H4-{B(C 6F5)2})(C6F5)] 10 are described. The crystal structures of compounds 4 and 10 have been determined. Initial electrophilic addition of the Lewis acid B(C6F5)3 occurs either by evo-addition to a carbon of a rj-cyclopentadienyl ring with formation of an cvo-{(C6F5)1B}C3Hj, or by formation of an M-u-H-B two-electron three-centre bond.
