Green and Facile Synthesis of New 3-(Phenylallylideneamino)indeno[1,2-d]imidazoles
A green and facile strategy has been proposed for the synthesis of previously unknown 3a,8a-dihydroxy-3-[(3-phenylprop-2-en-1-ylidene)amino]-2-sulfanylidene-2,3,3a,8a-tetrahydro-1H-indeno[1,2-{und}]imidazol-8-one and 3a,8a-dihydroxy-3-[(3-phenylprop-2-en-
Basic alumina as an efficient catalyst for preparation of semicarbazones in solvent free conditions
An efficient and simple procedure for conversion of different classes of aldehydes and ketones into the corresponding semicarbazones with semicarbazide hydrochloride using basic alumina is studied.
