Abstract: Abstract A general approach to prepare unsymmetrical sulfamides is described. This method relies on the activation of sulfamic acid salts with triphenylphosphine ditriflate, and subsequent trapping by a nucleophilic amine. This strategy improves access to… read more here.

Abstract: A general approach to access sulfamate esters through preparation of sulfamic acid salts, subsequent activation with triphenylphosphine ditriflate, and nucleophilic trapping is disclosed. The method proceeds in modest to excellent yields to incorporate nucleophiles derived… read more here.
