Wu, Liqiang,Yan, Yunhui,Yan, Fulin
experimental part, p. 149 - 154 (2012/02/16)
An efficient method has been developed for the synthesis of dithienylmethanes via bisarylation of aldehydes with thiophene in the presence of melamine trisulfonic acid as a catalyst under solvent-free conditions.
Silica sulfuric acid as heterogeneous and recoverable catalysts for the synthesis of dithienylmethanes under solvent-free conditions
Wang, Yingling,Lu, Guangzhou,Wu, Liqiang
experimental part, p. 4221 - 4222 (2012/01/04)
An efficient synthesis of dithienylmethanes from the reaction of thiophene and aromatic aldehydes under solvent-free conditions in good to excellent yields and short reaction times using reusable silica sulfuric acid as heterogeneous acid catalyst has bee
Unique versatility of Amberlyst 15. An acid and solvent-free paradigm towards synthesis of bis(heterocyclyl)methane derivatives
Singh, Kamaljit,Sharma, Shivali,Sharma, Amit
scheme or table, p. 34 - 37 (2011/10/17)
Bis(heterocyclyl)methanes, key intermediates for a variety of chemical, biochemical and material science relevant targets, have been obtained in a synthetically useful manner using Amberlyst 15 ion-exchange resin. This method promises versatility, cost-ef
The reaction of N-tosyl imines with heteroaromatic compounds: A new access to triheteroarylmethanes
Temelli, Baris,Tasgin, Dilek Isik,Unaleroglu, Canan
experimental part, p. 6765 - 6768 (2010/10/01)
Useful triheteroarylmethanes were prepared by the double Friedel-Crafts reaction of a wide variety of aromatic N-tosyl imines with furan, thiophene, and pyrrole in the presence of Cu(OTf)2 and Montmorillonite K-10 clay catalysts.
Efficient synthesis of triarylmethanes via bisarylation of aryl aldehydes with arenes catalyzed by silica gel-supported sodium hydrogen sulfate
Leng, Yixin,Chen, Fang,Zuo, Li,Duan, Wenhu
experimental part, p. 2370 - 2373 (2010/06/13)
An efficient synthesis of triarylmethanes has been developed via bisarylation of aryl aldehydes with arenes catalyzed by silica gel-supported sodium hydrogen sulfate in a solvent-free system. The new method features high yield, mild reaction conditions, a
