설명

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).
