A convenient and practical method for the one-pot, three-component synthesis of terminal vinylphosphonates from aldehydes, nitromethane and trialkylphosphites through a tandem Henry-Michael reaction followed by nitro elimination in the presence of 5-hydroxypentylammonium acetate (5-HPAA) as a task-specific ionic liquid offers good yields of the products under mild reaction conditions.
