Abstract :
A mild, simple, environmentally benign
catalytic protocol for transforming epoxides (oxiranes)
into their respective 1,3-dioxolanes. The different
epoxides with ketones give exclusively 1,3-dioxolanes
catalyzed by sulfated yttria-zirconia with moderate to
good yields (A [3+2] cycloaddition approach). The GC
and GC-MS analysis shown in most instances that the
product obtained was exclusively 1,3-dioxolanes. The
catalysts were characterized by using X-ray powder
diffraction (XRD), EDAX, FTIR, Thermal methods, and
n-butylamine potentiometric titration method. Simple
work-up, mild process conditions, and solvent-free
approach make the procedure superior to current
techniques.
