실험 절차

A mixture of 8.0 g of terephthalic acid (48 mmol), 0.10 g of Re2(CO)10 (0.15 mmol) and 17.3 g of toluene was subjected to vinylation at 140° C., a nitrogen pressure of 2 bar and an acetylene pressure of 18 bar for 6 h. Divinyl terephthalate was obtained, which was detectable by means of GC-MS analysis.
