Investigation of efficient synthesis of 1, 8-dioxo-octahydroxanthene derivatives under solvent-free grinding method

Article history: Received March 27, 2013 Received in Revised form July 27, 2013 Accepted 22 August 2013 Available online 24 August 2013 In these studies, we had observed polyaniline (PANI) supported p-toluene sulfonic acid (TsOH) and FeCl3(PANI-TsOH, PANI-FeCl3) as excellent reusable solid acid catalysts for the synthesis of 1, 8-dioxo-octahydroxanthene derivatives 4(a-g) under solvent-free grinding method at mild conditions. Additionally, in the same optimized condition ferric nitrate nonahydrate also acted as (non-reusable) very reactive inexpensive Lewis acid catalyst. The ferric nitrate nonahydrate lost its activity in the form of Clayfen (Clay-supported ferric nitrate) catalyst. © 2013 Growing Science Ltd. All rights reserved.

Green chemical approach for facile one-pot synthesis of 2,4,8-trisubstituted-1,5-benzothiazepines and their dioxides under microwave irradiation

2,4,8-Trisubstituted-1,5-benzothiazepines (synthesized ‘in situ’) have been selectively oxidised to the corresponding sulfones via a one-pot procedure in 9 min. with 91% yield under microwave irradiation coupled with clay-supported ferric nitrate.

Thiocarbonyls into carbonyls: efficient conversion by clay-supported ferric nitrate

A simple and inexpensive procedure is proposed for achieving the title transformation. The method works best with thiobenzophenones (60–100 % yields).

ChemInform Abstract: Some Organic Syntheses with Clay‐supported Reagents

A B S T R A C T : Some uses of clay-supported reagents in fine organic synthesis are discussed, in particular the catalysis of the phase-transfer preparation of formaldehyde acetals by quaternary ammonium montmorillonites. preparation and some applications of clay-supported ferric nitrate, a new reagent which oxidizes alcohols into carbonyl derivatives, couples thiols into disulphides, nitrates phenols, and oxidatively couples pyrrole and benzaldehyde into tetraphenylporphyrin, are also described During the last few years, organic chemists have paid considerable attention to organic reactions effected by reagents immobilized on highly-divided solids, for which the name 'supported reagents' has been coined (Posner, 1978; McKillop & Young, 1979; Frechet, 1981). These reagents may be placed in two groups depending on the nature of the

Conversion of n,n-dimethylhydrazones to carbonyl compounds by clay-supported ferric nitrate

Cleavage of N,N-dimethylhydrazones is cleanly effected with good yield in dichloromethane using the extremely inexpensive clay-supported ferric nitrate.

Efficient conversion of hydrazines to azides with clay-supported ferric nitrate

Azides are prepared in good yield in dichloromethane under mild conditions using the extremely inexpensive clay-supported ferric nitrate.
