Reaction Conditions:
with tris(pentafluorophenyl)borate in tolueneReflux;
Steps:
2.2
To the reaction flask into n-octanol 27.4 g (0.21 mol), ethyl gallate 39.6g (0.2mol), tris (pentafluoro-phenyl) borane 4g (0.008mol) and 350 g of toluene, with heating, the system became For clarification, the reflux reaction was further slowly increased for 5 to 6hours, and the raw material was The added refluxing materials sulfhydryl silica gel 7g performedfor capture of heavy metals, hot filtered, the filtrate was concentrated to recover the solvent and then added dropwise to 150g room temperature water slurried, filtered and dried to give electricalsub-level gallate Octyl 53.1g, HPLC: 98.7 %, yield: 94.1%.
