The route is highly selective for ortho-formylation and also specific towards monoformylation. The crucial role of added bases is emphasized.Giovanni...
Phenolic derivatives are forrnylated selectively ortho to the hydroxy group by paraformaldehyde with magnesium dichloride-triethylamine as base. With allcy...
General methods have been developed for the ortho alkylation and the ortho formylation of phenols. The processes are based on the rearrangement of ylides formed from the treatment of oxasulfonium salts with triethylamine. The oxasulfoniu...
2-Hydroxymethylphenols have been prepared in good yield by reduction with sodium borohydride of the precursor aldehydes, obtained regiospecifically from re...
This reagent can be used for the efficient and selective formylation of alcohols in the presence of phenols in a relatively short reaction time and high ...
The Duff reaction is one of the most employed methods for the ortho-formylation of phenols; however, not much is truly known about its mechanism. Using DFT calculations, we disclose the first theoretical study regarding the selectivity-d...
Several methods are available for the direct formylation of phenols, but most of them suffer from lack of regioselectivity. Moreover, several of the method...
