Claisen Rearrangement In Catechols - Synthesis of 4-Allylcatechol - [www.rhodium.ws]
From the residue consisting of unreacted catechol, potassium carbonate and potassium bromide, catechol (9.9 g.) was recovered by extraction with ether.
Acryloyl catechol — In a flask, phosphorus pentoxide (45 g.) and phosphoric acid (20 ml.) were mixed to a homogeneous mass, heated to 110°C and catechol (5.5 g.; 0.05 mole) and acrylic acid (3.6 g.; 0.05 mole) were added to it all at once.
