Phosphazene Bases

Phosphazene base reagents are available as monomeric (P1 and BEMP), dimeric (P2), and tetrameric (P4) bases with different side chains to control their sterical hindrance.

Phosphazene Superbase-Mediated Regio- and Stereoselective Iodoaminocyclization of 2-(1-Alkynyl)benzamides for the Synthesis of Isoindolin-1-ones.

Saurabh Mehta et al.

The Journal of organic chemistry, 84(9), 5492-5503 (2019-04-16)

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
