Synthesis of asymmetric triarylbenzenes by using SOCl2-C 2H5OH reagent

A simple and efficient method for synthesis of asymmetric branched functionalized triarylbenzenes is presented. The dypnone reacting with different substituted acetophenones, corresponding asymmetric 1,3,5-triarylbenzenes were obtained in the presence of catalytic amounts of sulfurous oxychloride in anhydrous ethanol.

The invention discloses a synthetic method for a 1,3,5-triarylbenzene compound. The method comprises the following steps: dissolving a chalcone derivative and inorganic alkali in dimethyl sulfoxide, carrying out reaction at 40 to 80 DEG C in the air for 3 to 8 hours, and carrying out separation and purification so as to obtain the 1,3,5-triarylbenzene compound, wherein a molar ratio of the chalcone derivative to the inorganic alkali is 1: 1-6; every mole of the chalcone derivative requires 4 to 8 mL of dimethyl sulfoxide; and the chalcone derivative has a general structural formula described in the specification, wherein Ar1 and Ar2 are aryl groups.

Pyrylium Compounds. 38. About the Ring Transformation of 2,4,6-Triarylthiopyrylium Salts by Acetic Acid Anhydride to Arylbenzenes and Thiobenzophenones

2,4,6-Triarylthiopyrylium salts 5 react in the presence of an appropriate condensing agent (sodium acetate, carbonate, methoxide, tert-butoxide or potassium acetate) with acetic acid anhydride to yield arylbenzenes 3 and thiobenzophenones 6.This ring transformation represents the first example of the conversion of the =S(+)- moiety into the thiocarbonyl group >C=S.Under the same conditions 3,5-dimethyl-2,4,6-triphenylthiopyrylium perchlorate (13) forms via -sigmatropic rearrangement the thiobenzophenone 15.The structure of the new compounds 6 was proved by spectroscopic methods as well as by degradation reactions.Thus, hydrogen peroxide converts 6a to the known benzophenone 4.Alkaline saponification gives the 2-hydroxy-benzophenone 8, whereas heating with hydrochloric acid causes a selective cleavage of the acetoxy group to the 2-hydroxy-thiobenzophenone 7.

Pyrylium Compounds. 37. Arylbenzenes from 2,4,6-Triarylpyrylium Salts and Carboxylic Acid Anhydrides

Refluxing 2,4,6-triarylpyrylium salts 1 with excess carboxylic acid anhydrides (RCH2CO)2O (2a : R = H, 2b : R = Me) in the presence of condensing agents like sodium or potassium acetate, sodium carbonate or methoxide, triethylamine or pyridine results in 1,3,5-triarylbenzenes 3 (R = H, Me).Under similar conditions, phenylacetic acid anhydride (2c), generated in situ from sodium phenylacetate and excess 2a or 2b, yields 1,2,3,5-tetraarylbenzenes 3 (R = Ph).Thus, the reaction 1 + 2 --> 3 represents a new and simple method for replacing the pyrylium heteroatom =O(1)- by the =CR- moiety (R = H, Me, Ph).The structure of the arylbenzenes 3 was proved by spectroscopic methods, by comparison with literature data or by independent synthesis.As by-products 2-acyloxy-benzophenones 10 are formed.Reaction of 3,5-dimethyl-2,4,6-triphenylpyrylium perchlorate (11) with acetic acid anhydride/sodium acetate (or sodium phenylacetate) takes another course leading to 2-acetoxy-3,5-dimethyl-4,6-diphenyl-benzophenone (15), whereas treatment of 11 with propionic acid anhydride/sodium acetate follows the reaction scheme 1 + 2 --> 3 giving 1,3,5-trimethyl-2,4,6-triphenylbenzene (16).The mechanisms of the different pyrylium ring transformations are discussed.
