摘要
Polyynes, a class of molecules described by the general formula H-(CdropC)(m)H (where m is an integer) can be synthesized using an electric arc between graphite electrodes submerged in an organic solvent such as methanol, n-hexane, n-dodecane, decahydronaphthalene or acetonitrile. When the electric are is used in acetonitrile at -40degreesC, polyyne chains of up to 18 carbon atoms (m = 9) have been produced together with monocyanopolyyne as by-product. The polyynes can be reduced to ene-ynes by shaking a hexane solution of them with Zn/HCl. (C) 2003 Elsevier Ltd. All rights reserved.
