Tritylium assisted iodine catalysis for the synthesis of unsymmetrical triarylmethanes

The combined Lewis acid catalytic system, generated from molecular iodine and tritylium tetrafluoroborate effectively catalyzed the Friedel-Crafts (FC) arylation of diarylmethyl sulfides providing an efficient access to various unsymmetrical triarylmethanes. The addition of tritylium and iodine created a more active catalytic system to promote the cleavage of sulfidic C-S bonds. This journal is

Method for catalytic preparation of triarylmethane compounds by using [EG]2[ZnCl2]

The invention relates to a method for catalytic preparation of triarylmethane compounds by using [EG]2[ZnCl2], especially to a method for catalytic preparation of the triarylmethane compounds by using a deep eutectic solvent [EG]2[ZnCl2] through Friedel-C

Simple Method for sp2-sp3 and sp3-sp3 Carbon-Carbon Bond Activation in 2-Substituted 1,3-Diketones

Simple and efficient methods were developed for sp2-sp3 and sp3-sp3 C-C bond-activation reactions of 2-substituted 1,3-diketones. 3-Substituted 3-bromopentane-2,4-diones were deacylated in the presence of an aromatic compound and a silica gel supported Bronsted acid containing sulfonic groups. The carbocation formed by cleavage of the sp3-sp3 C-C bond of the dione alkylated the aromatic compound.

Organocatalytic friedel-crafts benzylation of heteroaromatic and aromatic compounds via an SN1 pathway

The Friedel-Crafts-type benzylation of various π-excessive heteroaromatic and aromatic compounds with trityl or benzhydryl halides was efficiently promoted by a thiourea catalyst. This is a novel example of thiourea catalysis of aromatic alkylation by way

Direct alkylation of aromatics using alcohols in the presence of NaHSO 4/SiO2

Simple and efficient procedure for alkylation of aromatics from alcohols in the presence of NaHSO4/SiO2 was developed. Various triaryl methanes were obtained in good yields in short reaction time. For instance the reaction of mesitylene with benzhydrol in the presence of NaHSO4/SiO2 gave the corresponding triaryl methane in a quantitative yield. NaHSO4/SiO2 was regenerated by simple treatment and could be recycled eight times without activity loss.

Nucleophilic deoxyfluorination of catechols

Nucleophilic deoxyfluorinaiton of one of the two hydroxyl groups of catechols has been developed via the Umpolung concept. This method was successively applied to naturally occurring catechols, such as catechins and dopamine, to produce novel fluorinated

Anomalous Acetoxylation of Aromatic Nuclei: Some Structural Requirements in the Substrate

For certain aromatic nuclei, bromination in acetic acid in the presence of pyridine is accompanied by nuclear acetoxylation.As first observed with galbulin, when two alkoxyl groups, one meta and one para to a benzylic centre of the substrate are present, acetoxylation occurs at the intervening ortho position.Under the given conditions, acetoxylation occurs at position 8 of 6,7-dimethoxy-1-phenyl-1,2,3,4-tetrahydronaphthalene, and at position 2 of 3,4-dimethoxy diphenyl and triphenyl-methanes.Acetoxylation does not occur in the absence of either of the alkoxy groups or in the absence of pyridine, not does it occur in the pendant ring of 1-(3',4'-dimethoxyphenyl)-1,2,3,4-tetrahydronaphthalene.These results are consistent with the earlier suggestion that the reaction occurs by way of initial oxidative formation of a doubly benzylic cation
