1,4-C,O-dianions, produced through concomitant acid / base and tellurium / lithium exchange reactions were generated. The di-lithium salts were transmetallated with CeCl 3 to the corresponding di-cerium salts and reacted with carbonyl compounds yielding spiroketals. The di-lithium entities were also converted into the corresponding cyanocuprates which add in a 1,4-maner to 2-cyclohexen-1- one giving 1,6-dioxigenated compounds.

The tellurium nuclear magnetic resonance spectrum of a chiral tellurium ferrocene (2) produces a single signal at different chemical shifts when solubilized together with different enantiomeric proportions of a chiral compounds.

An efficient and mild methodology for oxidation of some organic compound is described using tetramethylammonium fluorochromate (TMAFC) under microwave irradiation.

The microwave-assisted reactions of substituted furo[3,2-b]pyrrole-5-carboxhydrazides 1 with 5-substituted furan-2-carboxaldehydes 2, thiophene-2-carboxaldehyde 3 and 2-formyl-4-methylfuro[3,2-b]pyrrole-5-carboxylate 4 have been studied under microwave irradiation. Reactions of 1 with 4-substituted 1,3-oxazol-5(4H)-ones 8 led to imidazole derivatives 9. The effects of hydrazones 5-7 on inhibition of photosynthetic electron transport in spinach chloroplasts were investigated.

The multigrams synthesis of Ibufenac is reported and the results of conventional and microwave heating are compared.

A fast and highly efficient microwave accelerated solution phase procedure for the synthesis of a series of 2-phenyl-3-(substituted-benzothiazole-2-yl) - 4[3H]-quinazolinone is developed and title compound was characterized by elemental analyses and spectral (IR, 1H NMR and EI-MS) data. The anticonvulsant activity of all the title compounds (3a-m &4a-m) were evaluated against Maximum Electroshock (MES) induced seizures and further more the compounds were evaluated against subcutaneous pentylenetetrazole (PTZ) induced seizures model in mice. The neurotoxicity was assessed using Rotorod procedure. All the test compounds were administered intraperitoneally at a various dose levels ranging from 7-200 mg/Kg body wt and the median toxic dose (TD50) and protection index (PI) values were determined and reported. In general compounds 3a-m were found to be more potent compared to compounds 4a-m. Among the compound tested , the compound 3e in 2-phenyl-3-(substituted-benzothiazole-2-yl) – 4-[3H]-quinazolinones series and compound 4l in 6,8, dibromo 2-phenyl-3-(substituted-benzothiazole-2-yl) – 4-[3H]-quinazolinones series were found to be the most potent.

Carboxymethylation reactions of aromatic amines and phenols with dimethyl carbonate were studied using microwave irradiation.

Pyrazole alkylation by benzyl, diphenylmethyl and trityl halides (chlorides and bromides) has been achieved by means of microwave irradiation. The structures and percentages of the different derivatives obtained have been determined by analytical methods: NMR spectroscopy plus gas chromatography coupled to mass spectrometry.

The microwave assisted oxidation of anthracene on heterogeneous catalyst is presented. As the matrix for different heteropolyacids used as a catalyst for oxidation reaction with hydrogen peroxide and its adduct with urea the conducting polyaniline was chosen. All the microwave processes were compared to conventional reaction carried out in the same temperature conditions.

Microwave assisted organic synthesis (MAOS) of N,N-diisopropyl enol carbamate of acetophenone is achieved in good yield when acetophenone, N,N-diisopropylcarbamoyl chloride and Hüning's base, DABCO or TMEDA were irradiated with microwaves. It is remarkable that reaction times are reduced from six days with conventional heating, to twenty minutes.
