An ion assisted ortho-specific phenol-formaldehyde condensation process, incorporating selective protecting-deprotecting methodology has been adapted to prepare a range of model novolac compounds which are ideal for studying crosslinking with hexamethylenetetramine.
Magnesium-mediated ortho-Specific Formylation and Formaldoximation of Phenols

Deprotonation of phenols using magnesium methoxide, followed by distillative removal of free methanol and addition of paraformaldehyde results in ortho-specific magnesium mediated formylation to give the corresponding salicyladehyde magnesium salts, from which the salicylaldehydes can be isolated by acidic work-up.Addition of aq. hydroxylamine sulfate to the salicylaldehyde magnesium salt, in place of the acid work-up, gives the corresponding salicylaldoximes.
