The Akatsuki caught sight of Deidara, and Pain ordered Itachi Uchiha, Sasori, and Kisame Hoshigaki to recruit him. Itachi made a bet with Deidara, saying if he lost, he would have to join Akatsuki. If Deidara won, he would leave him alone. Deidara was easily defeated by Itachi's Sharingan and joined Akatsuki. This fight created Deidara's loathing for the Sharingan, and a huge impact on his egotistical personality.
There aren't any episodes with them together like talking, but there is one with Itachi, Kisame, and Sasori trying to talk Deidara into joining the akatsuki in Shippuden episode 124. And there is a few episodes in the beginning of Shippuden where they fight different people indirectly.
deidara killed himself because he blew himself up to kills sasuke but he failed
Some of them died this people are Deidara, Sasori, Kakuzu, Hidan, and Itachi
Deidara, throughout the entire Naruto series after he joins the Akatsuki, has a grudge agenst Uchiha Itachi, and all uchihas, because Itachi is the one who made Deidara join the Akatsuki in the first place. Deidara, while fighting Uchiha Sasuke in Shippuuden, chewed and ate some of his clay turning himself into a human bomb in order to kill Sasuke. He blew himself up but, unfortunately, instead of killing Sasuke, Deidara killed himself.
