Description

Application

Phosphazene Bases: a Family of Extremely Strong, Non-Ionic, Non-Charged Nitrogen–Bases

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.
