Description and Uses

4,6-Dimethyl-α-pyrone (Me₂1) has been used in the preparation of G₄C{Me₂1} via reacting with tetra-p-sulfocalix[4]arene (C) and guanidine hydrochloride (GCl). It may be used in the preparation of host-guest complex G₄C{Me₂1} by reacting with crystalline guanidinium-sulfonate-calixarene (G₄C). This complex on UV irradiation afforded 1,3-dimethylcyclobutadiene (Me₂CBD).
