Initially, the experiment focused on the allylation of benzil (2b), which has a higher reactivity than a simple ketone due to its electron-withdrawing group. To generate HInCl 2 , the InCl 3 -Bu 3 SnH system was used. [8] After the reaction at room temperature for 14 hours, α-adduct 4ab was obtained (Table [1] , entry 1). [9] [10] As we have previously reported, [4] no α-adducts had been obtained in the reaction of simple ketones. When the reaction period was reduced from ...
