The short high-temperature reaction of diethyl phosphonate with 3,5-di-tert-butyl-4-hydroxybenzaldehyde at molar ratio 2:1 yields diethyl-2-ethoxy-3,5-di-tert-butyl-4-hydroxybenzylphosphonate instead of the expected diethyl-α-hydroxy-3,5-di-tert-butyl-4-hydroxybenzylphosphonate.The same reagents taken in a 3:1 ratio react to form tetraethyl-3,5-di-tert-butyl-4-hydroxybenzylidenebisphosphonate.The same bisphosphonate is formed on treating 3,5-di-tert-butyl-4-hydroxybenzaldehyde with an excess of triethyl phosphite.
