N-Allyl-2-methyl aniline 1a], N-allyl and N-(2'-methyl allyl)-N-methyl anilines [1b & 1c, respectively] undergo the 3-aza-Cope rearrangement in presence of HY-Zeolite, HEMT and HZeolite beta in hexane at 80 degrees C to give Indoline derivatives as the major product.

Chemically reactive carbocyanine dyes incorporating an indolium ring moiety that is substituted at the 3-position by a reactive group or by a conjugated substance, and their uses, are described. Conjugation through this position results in spectral properties that are uniformly superior to those of conjugates of spectrally similar dyes wherein attachment is at a different position. The invention includes derivative compounds having one or more benzo nitrogens.
