All sensitive materials were transferred under inert atmosphere conditions, using a dry box or Schlenk apparatus. Solvents were dried by reflux over Na or H2Ca in an Ar atmosphere. All starting materials were [wiki]pu[/wiki]rified by crystallization or distillation under low pressure.

General Procedure for the Titanium-Induced Couplings. TiCl3 (1.03g, 6.7 mmol) and 1.5 g of Zn-Cu coupleb were covered with 20 mL of dry solvent . The mixture was refluxed for 1 h with effective stirring under Ar atmosphere. .A solution of 3.35 mol of the carbonyl compound in 5 mL of dry solvent was added at once, and refluxing was continued for the amount of time indicated in Table I. To the reaction mixture was added 25 g of silica gel, and the solvent was removed under vacuum, the residue being incorporated at the top of a silica gel column. Stilbenes were eluted with CH2Cl2, normally giving crystalline compounds.
