Abstract

Enaminohydroxyketones, formed from 1,3,3-trimethyl-2-methyleneindoline and ortho-acetoxyaromatic acid chlorides, are converted by heating with phosphorus oxychloride in dichloroethane and subsequent treatment with alkali to 4-chlorosubstituted spiropyranes of the indole series; these, in contrast to the unsubstituted analogs, do not show photochromic properties.
