-
Paragraph 0054-0063; 0091-0093, (2021/02/06)
The invention discloses a method for hydrocarbylation synthesis of trisubstituted and tetrasubstituted olefins from non-terminal olefins, wherein the method comprises the steps: carrying out hydrocarbylation reaction on the non-terminal olefins and sulfoxide in the presence of ferric salt and hydrogen peroxide, carrying out one-pot reaction on disubstituted non-terminal olefins to generate the trisubstituted olefins, and carrying out one-pot reaction on the trisubstituted non-terminal olefins to generate the tetrasubstituted olefins. In the method, sulfoxide is simultaneously used as a hydrocarbylation reagent and a solvent of olefins, and one more hydrocarbyl substituent is added to a reaction product compared with a double-bond carbon atom of a reactant, so that an olefin carbon chain isincreased; the reaction conditions are mild, the selectivity is good, the yield is high, and industrial production is facilitated.

-
Paragraph 0066-0072, (2021/11/06)
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.
A one-pot cross-pinacol coupling/rearrangement procedure
Scheffler, Ulf,Mahrwald, Rainer
, p. 1970 - 1975,6 (2012/12/12)
A new catalytic retro-pinacol/cross-pinacol reaction, followed by subsequent rearrangement or deoxygenation of the intermediately formed vicinal diols, is described. This operationally simple one-pot protocol allows isolation of geminal α,α-diphenyl ketones or 1,1-diphenyl alkenes with high yields and selectivities. Copyright
