of vinyl triflates with higher-order stannyl cuprates was found to provide a convenient method for the preparation of vinyl stannanes. Since vinyl triflates can be regioselectively prepared from ketones this then provides overall regioselective entry to vinyl lithiums from vinyl triflates via their corresponding stannanes. This is an improvement on a previous method for the preparation of vinyl stannanes
