Reaction Steps

1,2-Bis-dodecyloxy-4-vinyl-benzene (JYC-II-004-A) was synthesized in 66% yield according to a simplified Wittig reaction procedure reported by Gaset and co-workers.3 The Pd-catalyzed Heck coupling reaction between 4,4′-dibromobenzil and 1,2-bis-dodecyloxy-4-vinyl-benzene gave 1,2-bis-{4-[2-(3,4-bis-dodecyloxy-phenyl)-vinyl]-phenyl}-ethane-1,2-dione (JYC-II-007-A) in 76% yield as a bright yellow solid. Bis{1,2-di-{4-[2-(3,4-bis-dodecyloxy-phenyl)-vinyl]-phenyl}-ethane-1,2-dithiolene}nickel (JYC-II-014-A) was prepared from the reaction between JYC-II-007-A and excess phosphorus pentasulfide in 1,4-dioxane at 110° C. for 5 h, followed by the reaction with NiCl2.6H2O. The product was isolated as a dark green solid. The synthesis of JYC-II-014-A is shown in FIG. 2.
