Abstract
A multistep process for preparing tetraselenofulvalenes involving the synthesis of 1,3-diselenole-2-selones and -2-thiones from diselenocarbamates and .alpha.-haloketones followed by coupling of the selone or thione using a dechalkogenizing reagent. New highly conductive salts obtained by coupling certain tetraselenofulvalenes with acceptor compounds are also disclosed.
