The invention discloses a preparation method of octyl methoxycinnamate (OMC). The preparation method comprises the following steps: firstly, uniformly stirring p-methoxybenzaldehyde, acetate, organic amine substances and a solvent, and controlling the temperature to be from 20 DEG C below zero to 10 DEG C; then dropwise adding a titanium tetrachloride catalyst, and after dropwise addition, rising the temperature to 10 to 40 DEG C, and carrying out reaction for 2 to 16h; after the reaction is completed, washing a reaction solution with dilute acid until being neutral, washing with water, drying an organic phase with anhydrous sodium sulfate, and carrying out solvent removal to obtain the octyl methoxycinnamate, wherein the yield reaches 98 percent or above. The preparation method has the characteristics of simpleness, convenience, easiness in control and industrial production, small environmental pollution, low energy consumption, capability of recycling materials, high purity and the like. The prepared octyl methoxycinnamate has the advantages of being colorless and transparent, high purity and the like and can be applied to the field of sun-screening cosmetics, chemical industry for daily supplies, plastics, rubber, coatings and the like.

Two Pd(II)-NHC complexes bearing benzimidazole and pyridine groups have been successfully prepared and fully characterized by NMR and X-ray diffraction analysis. The structure of palladium complexes are a typical square-planar with palladium surrounded by two pairs of trans-arranged benzimidazole and carbene ligands. The Pd-NHC complexes have been proved to be a highly efficient catalyst for the Mizoroki-Heck coupling reaction of aryl halides with various substituted acrylates under mild conditions in excellent yields.
