In ionicliquid [bmim]BF4, SnCl2·2H2O acts as an inexpensive and efficient metal salt for carbonyl allylation. By applying ionicliquid, some previously reported serious operational problems associated with the SnCl2-mediated allylation reaction are avoided. Furthermore, ketones, which are less reactive than aldehydes, can also be allylated in high yields with this system.
