catalysis of hydroxyapatite-supported copper (I) producing a variety of functionalized cinnamonitriles in high yields. The stereochemistry of the styrenyl double bond is preserved during the process providing the same stereoisomer of product.
An efficient cyanation of styrenyl bromides by K4[Fe(CN)6] has been achieved under the catalysis of hydroxyapatite-supported copper(I) producing a variety of functionalized cinnamonitriles in high yields. The stereochemistry of the styrenyl double bond is preserved during the process providing the same stereoisomer of product.
