5-(1,3-Dioxolan-2-yl)-2-furanylzinc bromide was easily prepared by the direct insertion of active zinc to 2-bromo-5-(1,3-dioxolane)furan under mild conditions. Of interest, the resulting organozinc was successfully coupled with aryl halides and acid chlorides affording the corresponding coupling products in good to excellent yields. (C) 2011 Elsevier Ltd.

5-bromo-2-furaldehyde or utilization of a neworganozinc reagent, 5-(1,3-dioxolan-2-yl)-2-furanylzinc bromide, which was easily prepared by the direct insertion of highly active zinc to 2-(5-bromofuran-2-yl-1,3-dioxolane. Of special note is the uniqueness of using a neworganozinc reagent, representing a first example of the direct synthesis of the corresponding organozinc halide. The subsequent coupling reactions
