Abstract
1,1-Diphenylethylene, 1,1-di-p-tolylethylene, 1,1-di-p-anisylethylene and 1,1-di(p-t-butylphenyl)-ethylene are converted in high yields (80- 90%) into the corresponding 3,3,6,6-tetraaryl-1,2-dioxans in the presence of oxygen and catalytic amounts of antimony(v) chloride in dichloromethane at -40° to -78° under irradiation from a tungsten lamp.
