Abstract
Abstract10-Telluroniaanthracene perchlorates react with nucleophiles (X−=halide, hydroxide, methoxide) via intermediate free telluroxanthyl radicals. With 9-aryl-10-telluroniaanthracene perchlorates, high yields of 9-aryl-9-X-telluroxanthenes are obtained, but with 10-telluroniaanthracene the principal product is 9,9′-bis(telluroxathenyl) as a result of rapid competitive dimerization.
