Selenostannylation of Arynes Produced by Silylaryl Triflates under Mild Reaction Conditions

Tributil[(fenilselanil)aril]estananas foram preparadas em bons rendimentos por reacao entre tributil(fenilselanil)estanana e 2-(trimetilsilil)aril triflatos na presenca de fluoreto de potassio e eter 18-coroa-6 em THF a 0 o C. Tributyl[(phenylselanyl)aryl]stannanes were prepared in good yields by reaction between tributyl(phenylselanyl)stannane and 2-(trimethylsilyl)aryl triflates in the presence of potassium fluoride and18-crown-6 ether in THF at 0 o C.
