In some cases the phenol is used to produce iso-octylphenol, isononylphenol, or isododecylphenol through addition reaction with long-chain olefins such as diisobutylene, tripropylene, tetra-polypropylene and the like, which are used in production of nonionic surfactants. In addition, it can also ...
Under these conditions, monoallyl 4-ACPH (product one) is obtained with a higher yield of 60%, than diallylcarbonate (second product) with a yield of 20%. Unlike the reaction reported in the literature, in which NaOH is used as a catalyst and water in which lower yields of 4-ACPH ...
Gallic acid (19) was converted to allyl ester 20 by reaction with allyl alcohol and EDCI. Upon treatment of 20 with Li2CO3 and methyl iodide, selective deprotonation and alkylation of the most acidic 4-OH proceeded smoothly to give 21. On the other hand, 3-OH selective alkylation was ...
at a liquid hourly space velocity in the range 0.3 to 2.5 and the phenol is recovered from the reaction product. The catalyst may be platinum-on-carbon, or other catalysts such as Pd, Ru, Rh, Ni or Co. The alkaline solution may be NaOH, but KOH, Na2CO3, NaHCO3, K2CO3, ...

Carbonyl-directed selective demethylation of 6 should lead to phenol 7, setting the stage for the attachment of the final aromatic moiety through an alkylation with benzyl halide 8 or a Mitsunobu reaction [16] with benzyl alcohol 9. With benzyl ether 10 in hand, the formation of the benzo...
When the acid addition was completed, the reaction was allowed to continue for 30 min at 0 ◦C, followed by 45 min at room temperature. The reaction was then cooled with an ice bath and 2 mL of NaHCO3 5% was added and diluted with Ethyl Acetate (EtOAc). The organic phase was ...
