<p>From <a href="http://naruto.wikia.com/wiki/Kamui" rel="nofollow">this</a> page about Kamui's abilities:</p>

<blockquote>
  <p>Despite not always being present, Obito could keep targets under genjutsu while they were confined inside this technique's pocket dimension, thus keeping them incapacitated for extended durations.</p>
</blockquote>

<p>Tobi knew that he cannot defeat the Fourth Hokage so easily while keeping Kyuubi under his control, since controlling Kyuubi itself consumes a lot of chakra. Hence, he may have tried sending Minato to Kamui's dimension to keep him out of the equation. </p>

<p>Minato can teleport to his Flying Thunder God formulas (specially marked kunai), but it isn't revealed whether he can do it from a different dimension.</p>

<p>During his fight against Minato, it seemed that Tobi was trying to send Minato to Kamui's dimension. Even if Tobi had succeeded, couldn't Minato just teleport to one of his special kunai using the Flying Thunder God technique? Tobi knew of the Flying Thunder God technique, so what did he want to accomplish by sending Minato to Kamui's dimension?</p>

Except that he probably can't teleport back if only half of him is sent there? Or one of the other possible witty guesses anyone can come up with without reading Tobis thoughts in the situation.

From [this](http://naruto.wikia.com/wiki/Kamui) page about Kamui's abilities:

> Despite not always being present, Obito could keep targets under genjutsu while they were confined inside this technique's pocket dimension, thus keeping them incapacitated for extended durations.

Tobi knew that he cannot defeat the Fourth Hokage so easily while keeping Kyuubi under his control, since controlling Kyuubi itself consumes a lot of chakra. Hence, he may have tried sending Minato to Kamui's dimension to keep him out of the equation.

Minato can teleport to his Flying Thunder God formulas (specially marked kunai), but it isn't revealed whether he can do it from a different dimension.
