Abstract
The first preparation of bis (η6‐arene)titanium(0) complexes was achieved by reduction of TiCl4 with the borate [BEt3H]− in the appropriate arene solvent. In contrast the same reduction in THF leads to soluble “TiH2”, which loses H2 when dried to give a substance which can be formulated as Ti · 0.5 THF with various amounts of residual hydrogen. X‐ray photoelectron spectroscopy and EXAFS analysis support the assumed oxidation state of zero for the titanium.Keywords
