Abstract
Our interest in these molecules stems from our desire to prepare an unusual type of carbene: a heteroatomsubstituted carbene possessing a triplet electronic ground state. These two features are generally mutually exclusive.* With the recent exception of HCI? all experimental evidence concerning heteroatom-substituted carbenes suggests that they possess singlet electronic ground states? Neverthelew, ab initio calculations predict either ...
