Phosphazene superbase P4- t-Bu mediated iodoaminocyclization of 2-(1-alkynyl)benzamides is reported. The reaction works under ambient conditions and instantaneously results in the synthesis of isoindolin-1-ones in 65-97% yields, in a regio- and stereoselective manner. The exclusive formation of products with Z-geometry
