Leafgreen can only trade between firered, ruby, sapphire, emerald, Pokemon colosseum, Pokemon xd gale of darkness, and migrate with diamond, pearl, platinum, heartgold and soulsilver it cannot trade with the original silver.
Either have someone trade it to you or migrate it from ruby/sapphire/emerald

You have to trade it from a different game or you need action replay for the cheat code. You can trade if from Pokemon Emerald, Sapphire, and Ruby to Pokemon migration center.
