일반 설명

P(t-Bu)3 Pd G2 (Chloro[(tri-tert-butylphosphine)-2-(2-aminobiphenyl)] palladium(II)) is a second generation (G2) precatalyst containing a biphenyl-based ligand. Product participates in various palladium catalyzed cross-coupling reactions, C-C, C-N and C-O bond formation reactions, and Suzuki-Miyaura coupling reactions. It generates active Pd catalyst at room temperature in the presence of weak phosphate or carbonate bases. It has been proposed as an active catalyst for use in Stille reactions of aryl halides (bromides and chlorides).

애플리케이션

P(t-Bu)3 Pd G2 (Chloro[(tri-tert-butylphosphine)-2-(2-aminobiphenyl)] palladium(II), Pd/P(t-Bu)3) may be used as catalyst in the following studies:
  • Synthesis of sterically hindered biaryls (tetra-ortho-substituted), via cross-coupling reactions of aryl chlorides.
  • Stille cross-couplings reactions of aryl chloride.
  • Synthesis of chloropeptin I, via Stille cross-coupling reaction.
  • Heck reaction.
  • Negishi cross-coupling reactions.

Pd/P(t-Bu)(3) serves as an unusually reactive catalyst for Stille reactions of aryl chlorides and bromides, providing solutions to a number of long-standing challenges. An unprecedented array of aryl chlorides can be cross-coupled with a range of organotin reagents, including SnBu(4).

Metal-catalyzed coupling reactions of aryl electrophiles with organometallics and with olefins serve as unusually effective tools for forming new carbon-carbon bonds. By 1998, researchers had developed catalysts that achieved reactions of aryl iodides, bromides, and triflates. Nevertheless, many noteworthy challenges

Scale-Up Guide: Buchwald-Hartwig Amination Reaction

All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use of standard Schlenk technique is recommended.
