Titanium magnesium amalgam

Reductive coupling of imines 43 (R1 = Me, Ph or 2-pyridyl R2 = Me, Pr, t-Bu or PI1CH2) in THF under the influence of a low-valent titanium species, produced by the action of magnesium amalgam on titanium(IV) chloride, gave the DL-diamines... [Pg.545]

Low-valent titanium metal species [Ti(II), Ti(I), Ti(0)] are generated by reduction of TiCl4 with magnesium amalgam" or by reduction of TiCl3 with either Li, K, Zn-Cu... [Pg.414]

PINACOLIC COUPLING Titanium(IV) chloride-Magnesium amalgam. [Pg.468]

The most general reagent for effecting this type of reaction is a combination of TiCU and a magnesium amalgam. The active reductant is presumably titanium metal formed by reduction of T1CI4. [Pg.262]

Alloys of reactive metals are often more pyrophoric than the parent metals. Examples are alloys of titanium with zirconium thorium with copper, silver or gold uranium with tin, lead or gold magnesium with aluminium hafnium with iron [1], Cerium amalgams and thorium-silver alloys are spontaneously flammable when dry [2], Individually indexed alloys are ... [Pg.360]

By use of weaker reductants, the C-C coupling can be stopped at the stage of the pinacols [48]. The best metals for achieving chemical pinacolization from ketones are magnesium in the form of its amalgam and mixtures of Zn-Hg with titanium tetrachloride (Scheme 11). In the latter reaction the Ti(II) species presumably initiates electron transfer [49]. [Pg.1129]
