Treatment of stilbene derivatives with aliphatic carbonyl compounds in the presence of trimethylsilyl chloride (TMSCl) and Mg metal in N,N- dimethylformamide (DMF) at room temperature brought about regioselective cross-coupling to give the corresponding phenethyl alcohols in moderate to good yields. These reactions may be initiated through one-electron transfer from Mg metal to the carbon-carbon double bond of stilbene derivatives to give the corresponding anion radical species, which were subjected to electrophilic attack of aliphatic carbonyl compounds followed by fast second electron transfer generating the corresponding α-benzyl anions.

Zirconacyclopropenes represented by Cp2Zr(PhCCPh)(PR3) (4), where PR3 is PMe3 or PMePh2, have been prepared by the reaction of Cp2Zr(PR3)2 with PhCCPh, isolated as yellowish crystals, and spectroscopically characterized.Zirconacyclopropenes readily react with proton donors, carbonyl compounds, e.g., acetone, and alkynes to induce dimerization of alkynes and are likely intermediates in the ZrCp2-induced bicyclization of enynes.
