Application

Phosphazene base P2-Et is an extremely strong, neutral nitrogen base. It gives excellent results where other bases fail

This strong non-ionic base has the ability to catalyze a wide variety of organic transformations such as:
  • Palladium-catalyzed cross-coupling reactions when used in combination with tBuXPhos or tBuBrettPhos G3 precatalysts.
  • Deprotonation of ortho-halobenzyl sulfones to generate α-sulfonyl benzylic carbanions.
  • Conversion of vinyl sufone to allyl sulfone.
  • α-Alkylation of 2-phenyl-2-oxazoline-4-carbonylcamphorsultam in the presence of tetrabutylammonium bromide.
