Silylstannation of terminal alkynes using a recyclable palladium(0) catalyst immobilised in an ionic liquid.
Silylstannanes can be regioselectively added across terminal alkynes in a quantitative fashion in the presence of a palladium(0) catalyst immobilised in the [bmim]PF6 ionic liquid which can be recycled without loss of activity.
