Tetrahydro-4H-pyran-4-one Chemical Properties,Uses,Production

Chemical Properties

colorless to light yellow liquid

Uses

Tetrahydro-4-pyrone is used in organic synthesis as building block for more complex chemical structures because it participate in a variety of cycloaddition reactions.

Purification Methods

Purify the pyrone by repeated distillation, preferably in a vacuum. [Baker J Chem Soc 296 1944, IR: Olsen & Bredoch Chem Ber 91 1589 1958.] The oxime has m 87-88o and b 110-111o/13mm [Cornubert et al. Bull Soc Chim Fr 36 1950]. The 4-nitrophenylhydrazone forms orange-brown needles from EtOH, m 186o [Cawley & Plant J Chem Soc 1214 1938]. [Beilstein 17 I 131, 17 II 287, 17 III/IV 4171, 17/9 V 21.]
