Oxygen or nitrogen? Radical chemists overwhelmingly choose to work with xanthates rather than dithiocarbamates, yet the latter offer a distinct advantage in the case of a new method for generating carbamoyl radicals. Functionalized lactams of various ring sizes can be prepared in an operationally simple procedure involving irradiation or heating in the presence of a radical initiator (see scheme).
