The Tailed Beasts are highly susceptible to genjutsu that stems from the Sharingan (or just the Sharingan in general), and likely don't have any defense against it. The reason why Sasuke didn't use genjutsu against Naruto is probably because he is a perfect jinchuriki. If genjutsu is used on Naruto, then Kurama can simply get him out of it. This is just like when Gyuki got Bee out of Sasuke's genjutsu. I think the way one can successfully use genjutsu on a perfect jinchuriki is if the genjutsu is used on both the jinchuriki and the Tailed Beast. This is probably how Tobi got Yagura, a perfect jinchuriki, under his control for many years. Sasuke has used genjutsu on Sai (though, not in combat), Deidara, Danzo, and Sakura (to shut her up). He also used his Sharingan to suppressed a small amount of Kurama's chakra and combat Itachi's genjutsu. The only person shown to consistently used use genjutsu in battle is Itachi.
