The reaction of di-tert-butyl selenoketone with propiolic acid gave 2H,6H-1,3-oxaselenin-6-one in 78% yield, whereas the reaction of di-tert-butyl thioketone with propiolic acid recovered starting thioketone almost quantitatively. On the other hand, the reaction of selenofenchone with propiolic acid gave 2H,6H-1,3-oxaselenin-6-one and Wagner-Meerwein rearranged product in good yields.
二叔丁基硒酮与丙炔酸的反应以 78% 的产率得到 2H,6H-1,3-oxaselenin-6-one,而二叔丁基硫酮与丙炔酸的反应几乎定量地回收了起始硫酮。另一方面,硒苯酮与丙炔酸的反应以良好的收率得到 2H,6H-1,3-oxaselenin-6-one 和 Wagner-Meerwein 重排产物。
