실험 절차

The synthesis of 6-hydroxy-2-vinylnaphthalene (HVN) was carried out by three step reactions starting from 6-hydroxy-2-naphthaldehyde. In the first step, 6-hydroxy-2-naphthaldeyde (HNAL) was protected with ethyl vinyl ether to give 6-(1-ethoxy ethoxy)-2-naphthaldehyde (EENAL). This was followed by the Wittig reaction of EENAL to yield 6-(1-ethoxy ethoxy)-2-vinylnaphthalene. Finally, this was deprotected using pyridinium p-toluenesulfonate to yield 6-hydroxy-2-vinylnaphthalene (HVN).
