Triphenylethylene multifunctional photoresponse compound as well as preparation method and application thereof

The invention provides a triphenylethylene multifunctional photoresponse compound. The structural formula of the triphenylethylene multifunctional photoresponse compound is as shown in formula 1, and in the formula 1, R1 and R2 are respectively and independently selected from one of bromine and hydrogen, and X is methyl or substituted methyl. The compound is a triphenylethylene pure organic room-temperature phosphorescent material, has the properties of photochromism, photodeformation, room-temperature phosphorescence and the like, and can be used in multiple fields of preparation of anti-counterfeiting marks, preparation of micro machinery and the like. The invention also provides a preparation method of the triphenylethylene multifunctional photoresponse compound. The preparation method has the advantages of cheap and easily available raw materials, few synthesis steps, simple preparation and mild reaction conditions, and is suitable for large-scale production. The invention further provides application of the triphenylethylene multifunctional photoresponse compound in preparation of an anti-counterfeiting mark and manufacturing of a micro machine.

Copper-catalyzed trifluoromethylation of organic zinc reagents with an electrophilic trifluoromethylating reagent

A copper-catalyzed trifluoromethylation of aryl, vinyl and alkyl zinc reagents with Togni's reagent was described. Mechanistic studies indicated that the aryl group is initially transferred from the zinc reagent to hypervalent iodine to form a tri-substituted hypervalent iodine intermediate. Consequent reductive-elimination via a concerted bond-forming step and/or radical pathway from this intermediate generates the trifluoromethylated arenes.

Sunlight-driven trifluoromethylation of olefinic substrates by photoredox catalysis: A green organic process

The principles and utility of photoredox catalysis in organic synthesis are described. After a brief description of the features of the two types of catalytic photoredox processes following the reductive quenching cycle (RQC) and the oxidative quenching cycle (OQC), the discussion is focused on organic transformations based on OQC, in particular the trifluoromethylation of olefinic substrates with electrophilic trifluoromethylating reagents furnishing solvolytic addition products and substitution products. It is concluded that catalytic photoredox systems are green from the point of view of harmfulness, safety, and energy source (visible light, including sunlight). Future prospects of photoredox catalysis will be also discussed.

Direct C-H trifluoromethylation of di- and trisubstituted alkenes by photoredox catalysis

Background: Trifluoromethylated alkene scaffolds are known as useful structural motifs in pharmaceuticals and agrochemicals as well as functional organic materials. But reported synthetic methods usually require multiple synthetic steps and/or exhibit lim

Niobium-catalyzed activation of CF3 group on alkene: Synthesis of substituted indenes

A CF3 group attached to an alkene functionality was activated by a zero-valent niobium catalyst to generate niobium alkenylcarbenoid species. The niobium carbenoid species then underwent insertion to an internal aromatic C-H σ bond to give inde

A facile stereocontrolled approach to CF3-substituted triarylethenes: Synthesis of panomifene

The stereoselective preparation and Pd-catalyzed cross-coupling reaction of boronates 2 provides a new general and convenient route to CF 3-substituted triaryl ethenes 3, in which the CF3 and Ar3 groups are cis to each other. The synthetic potential was demonstrated by the total synthesis of panomifene (Ar1 = Ar 3 = Ph, Ar2 = 4-(OHCH2CH2NHCH 2CH2O)-C6H4). Bpin = (pinacolato)boryl.

Preparation of α- or β-trifluoromethylated vinylstannanes and their cross-coupling reactions

α - or β-Trifluoromethylated vinylstannanes 1, 2a, 3 and 4 were prepared form 1,1-bis(phenylthio)-2,2,3,3,3-pentafluoropropylbenzene (5) via several steps. The cross-coupling arylation reactions of 1-4 with aryl iodides bearing a bromo, methoxy, methyl, n

Dissimilar reactivities of diastereomeric 1,1,1-trifluoro-3-(4-methoxyphenyl)-2,3-diphenylpropan-2-ols in an attempted elimination reaction

Attempted dehydration of a diastereomeric mixture of 1,1,1-trifluoro-3-(4-methoxyphenyl)-2,3-diphenyl-propan-2-ols (6a) with thionyl chloride in the presence of pyridine afforded the rearranged derivative 8 as the main product and only small amounts of the expected olefins (4, 5). Similar treatment of (2RS,3RS)-6a gave the rearrangement product 8 exclusively, while transformation of (2RS,3SR)-6a resulted in the formation of compounds 4, 5 and 8. The different reactivity of the diastereomers is rationalised.

A new method for the preparation of perfluoroalkylated triphenylethylene derivatives

The reaction of perfluoroalkylated dithioketals 1 with 2.1 equiv. of phenyllithium afforded the corresponding vinyl sulfides 2 in good yields. Treatment of vinyl sulfones 3, obtained from the oxidation of 2, with phenyllithium derivatives resulted in the
