New precursors for synthesis of sterically hindered nucleophilic heteroaromatic carbenes, diadamantyl substituted amidine and benzimidazolium salts, were elaborated. It was found a new autoreduction of azolium formates that proceeds via carbenic intermediates. Product Description popup.authors popup.nrat_date 2020-04-02 Close
