The present invention relates to a novel method for preparing bis(3-aminophenyl) disulphides of the general formula (I) and 3-aminothiols of the general formula (II), ##STR00001##
where X,Y have the meanings stated in the description,
which serve as intermediates for the preparation of phenyl sulphoxides having insecticidal, acaricidal and nematicidal activity.

On use of a sulfonium salt of specific structure as PAG, acid diffusion is suppressed. A resist composition comprising the sulfonium salt forms a pattern with improved lithography properties including EL, MEF and LWR when processed by lithography.

In one aspect, the invention provides a method of promoting a carbon-sulfur bond forming reaction. In certain embodiments, the reaction comprises cross-coupling of a(n) (hetero)aryl halide with a thiol to form the carbon-sulfur bond, wherein the method is promoted by light irradiation in the absence of a photocatalyst. In other embodiments, the cross-coupling reaction can be promoted through visible light irradiation, including sunlight.
