Pan, Wenjing published the artcileA mild and practical method for deprotection of aryl methyl/benzyl/allyl ethers with HPPh2 and tBuOK, Quality Control of 93-04-9, the publication is Organic & Biomolecular Chemistry (2021), 19(35), 7633-7640, database is CAplus and MEDLINE.
A general method for the demethylation, debenzylation, and deallylation of aryl ethers ROMe (R = C6H5, 3-FC6H4, 2-naphthyl, etc.), R1OCH2Ph (R1 = C6H5, 5,6,7,8-tetrahydronaphthalen-2-yl, 2-naphthyl, etc.) and R2OCH2CH=CH2 (R2 = C6H5, 2,3-dimethylphenyl, 1-naphthyl, etc.) using HPPh2 and tBuOK is reported. The reaction features mild and metal-free reaction conditions, broad substrate scope, good functional group compatibility, and high chem. selectivity towards aryl ethers over aliphatic structures. Notably, this approach is competent to selectively deprotect the allyl or benzyl group, making it a general and practical method in organic synthesis.
