title: Sterically demanding imidazolinium salts through the activation and cyclization of formamides.
abstract: A new protocol was developed for the synthesis of sterically demanding imidazolinium salts. This procedure was adopted for the synthesis of seven NHC salts, including ones that were demonstrated to be inaccessible using the conventional orthoformate ester type cyclization method.
