Polyfunctionalized phenols

One may note that the titration of the humic acid - because of its polyfunctionality - is less steep than that of the acetic acid-phenol mixture. 

The naphthalene-catalyzed (3-12%) lithiation of deprotonated chloro phenols and anilides 236 performed with n-butylUthium in THF at 0 or —78 °C, respectively, gave the corresponding functionalized aryllithium intermediates 237 which, by reaction with electrophiles and final hydrolysis, yielded the corresponding polyfunctionalized molecules 238 (Scheme 79) . 

Polynuclear Phenol—Glycidyl Ether-Derived Resins. This is one of the first commercially available polyfunctional products. Its polyfunctionality permits upgra ding of thermal stability, chemical resistance, and electrical and mechanical properties of bisphenol A—epoxy systems. It is... 

A catalytic triple domino Michael-aldol-oxa-Michael reaction of acetaldehyde with ( -2-(2-nitrovinyl)phenols catalyzed by (R)-2- diphenyl [(trimethylsilyl)oxy] methyl pyrrolidine followed by a sequential one-pot Wittig, Michael/Wittig-Horner reactions with PPh3=CHC02Et was applied to the asymmetric synthesis of polyfunctionalized chromans (14EJO3076).
