Efficient synthesis of π-acidic phosphorus-containing porous polymer supported catalysts for hydroformylation of olefins

Rh/POLs-BPa&PPh 3 catalysts have been synthesized using magnolol as the raw material for hydroformylation affording linear aldehydes in yields (79.8–90.6%) with regioselectivities ( l / b = 23.4–89.9) and high catalytic activities (TON up to 9950).
