Catalytic ethenylation reaction of phenol using SnCl4. [figure: see text] Ethenylation reaction of phenol with silylethyne at the o-position is catalyzed by the SnCl4-BuLi reagent. While turn over numbers (TONs... K Kobayashi,M Yamaguchi - 《Organic Letters》 被引量: 26发表: 2001年 High...
Alkylation of indoles with α,β-unsaturated ketones in presence of a clay mineral catalyst. Mn +-Mt (M = Al, Zr) efficiently catalysed the alkylation of activated aromatic compounds (phenol, anisole, etc.) with aldehydes and ketones (Scheme 9.6). A13 +-Mt exhibited significant activity (...
ADLER Phenol Oxidation Also known as Adler–Singh. Oxidation of o-alkoxyphenols with sodium metaperiodate to afford 6,6-spiro-2,4-cyclohexadienones, e.g. 2, 5 which dimerize spontaneously to a Diels– Alder adducts 3, 6. OH OH O O NaIO 4 O O O O 4 5 6 OH CH 2 OH NaIO 4 4...
Hydroxymethylation.Condensation of phenols with aldehydes takes place readily in the presence of either acidic or basic catalysts. The most important example is the reaction between phenol and formalin, usually carried out in the presence of aqueous sodium hydroxide, which gives a mixture ofo-andp-hy...
