The condensation of asymmetric I~-diketones with (x-oximinoacetoacetate esters affords pyrroles regioselectively. The mechanism of the regioselectivity is studied using ~C-NMR spectroscopy. Pyrrole having a neopentyl group at the 4-position is synthesized by the method, and further converted to a st

The physical properties of semiconductors define to a great extent the performance of photoelectrochemical (PEC) cells. With a band gap of 1.7 eV, cadraium selenide is an attractive candidate as photoelectrode in PEC cells for the conversion of light into electricity. Polycrystalline films are used
