HelloSorry to say but you cant trade Pokemon from pearl to leafgreen but you can migrate Pokemon from leafgreen to pearl via the pal park
On Pokemon Pearl's title screen, if the Pokemon LeafGreen game is in the GBA slot, click on "Transfer From LeafGreen" and you can choose six Pokemon from LeafGreen to transfer to Pearl, but be careful-you can't trade them back.
