Pyridine → Bis(propargyl)terephthalate

Participants

Reaction Steps

To a mixture of 10.15 g. of terephthaloyl chloride, 8.41 g. propargyl alcohol and 200 ml. anhydrous ether at 5° under nitrogen is slowly added with stirring 16.1 ml. of pyridine. The reaction mixture is stirred for 4 hours at 5° and for 21/2 hour at room temperature. Water (2 ml.) is added and the mixture is stirred for 1/2 hour. Additional water (100 ml.) is added, the organic layer is extracted with ether and pentane and the reaction mixture is worked up using the procedure of Example 1 to yield bis(propargyl)terephthalate, m.p. 109-109.5.
