- A novel one-pot synthesis of substituted pyridazines: A general method of preparation of 3,4,6-tri aryl pyridazines
-
3,4,6-triaryl pyridazines 4 were conveniently prepared in one step by the condensation of aryl methyl ketones and 1,2-diketones in presence of base, followed by cyclisation with hydrazines.

- Microwave-assisted Diels-Alder reaction supported on graphite
-
The coupling of graphite (as a support) with microwaves (as an energy source), a new type of "dry reaction", was studied for some Diels-Alder reactions involving anthracene and azadienes. Graphite is responsible for a high-temperature gradient leading to increased reaction rates as compared to conventional procedures using a solvent. VCH Verlagsgesellschaft mbH, 1996.

- SYNTHESIS OF 4-(TRIBUTYLSTANNYL)PYRIDAZINES BY INVERSE ELECTRON-DEMAND DIELS-ALDER REACTION OF 1,2,4,5-TETRAZINES WITH TRIBUTYLSTANNYLACETYLENES
-
Inverse electron-demand Diels-Alder reaction of 3,6-disubstituted 1,2,4,5-tetrazines with tributylstannylacetylenes containing a substituent gave 4-(tributylstannyl)pyridazines.Particularly, dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate gave 4-(tributylsta
