A process for producing a stable triggerable dioxetane comprising; (a) reacting a vinyl sulfide compound containing a sulfur-substituent SR.sub.4, wherein R.sub.4 is an organic group containing 1 to 20 carbon atoms and optionally heteroatoms, with oxygen and light in the presence of a photosensitizer to form an intermediate sulfur-substituted dioxetane compound; and (b) reacting the sulfur-substituted dioxetane compound with an electrophilic compound E--Y and a hydroxylic compound R.sub.5 OH selected from the group consisting of alcohols, phenols and carboxylic acids or their salts and containing an OR.sub.5 group to replace the SR.sub.4 group of the dioxetane with the OR.sub.5 group.
