The reaction at room temperature, between ketone phenylhydrazones and phosphorus trichloride gives the corresponding 2,3-disubstitutedindoles in high yields (70–90%)
Pyrrole and indoles react smoothly with alkyl halides such as allyl bromide, prenyl bromide, crotyl bromide and propargyl bromide in the presence of zinc metal in THF to afford the corresponding 3- and 2-alkyl pyrrole and 3-alkyl indole derivatives in good yields with high regioselectivity.
