Only what episode does he really attempt to kill Sakura, there are upcoming ones but those will be unintentional or intentional but not by his own hand (using Sakura and kakashi as collateral damage really) and the other one he didn't really try to kill her. The episode was right after his fight with danzo so 212-213 because the sasuke vs danzo fight is about 50 to 60 minutes roughly in length and started on episode 209.
