A Molecular Electron Density Theory (MEDT) study is presented here for [3+2] cycloaddition (32CA) reactions of three trimethylsilyldiazoalkanes with diethyl fumarate. The presence of silicon bonded to the carbon of these silyldiazoalkanes changes its structure and reactivity from...
Novel, less toxic, more effective catalysts were used to synthesize various flavones under auto clave conditions. Substituted o- hydroxyl acetophenones and benzaldehydes were reacted in-presence of 2, 4, 6-trimethylpyridine, a pinch of TiCl4 and yielded chalcones. Equimolar ratio...
