The specific solvent effect of dimethylether is studied for two possible chemical reactions involving dialkylzirconium (ZrCl 2 Et 2 ) and formaldehyde (H 2 CO). Using Density Functional Theory (B3LYP) and qualitative arguments, it is shown that such a polar solvent favors the ZrCl 2 (Alkene) formation by coordinating to the metal. Such a stable system can react further through alkene—solvent—formaldehyde exchange to spontaneously give the cyclization product. In a polar solvent, where such coordination cannot be envisaged, the preferred path gives the hydrometalated product directly from the dialkylzirconium reagent. © 2005 Wiley Periodicals, Inc.
