ABSTRACT:
Disclosed are new indole derivatives of the following general formula (I): ##STR1## and a process for producing the derivatives (I) by irradiating a solution of a triazolylnaphthalene derivative of the following general formula (II) in a solvent with light: ##STR2## wherein R' represents a hydrogen atom, a halogen atom, an alkyl group, a nitro group or a ##STR3## groups, n represents a number of 1 to 2, and when n is 2, two R groups may be either the same or different from each other and R.sub.n is the same as R'.sub.n or represents a ##STR4## group ortho-condensed with the naphthalene ring: W and Z each represent a hydrogen atom, a halogen atom, an alkyl group, a carboxyl group or an ester group thereof, n represents a number of 1 or 2, and when n is 2, two W groups and two Z groups may be either the same or different from each other, respectively.
