Description

General description

SPhos Pd G3 is a third-generation (G3) Buchwald precatalyst that can be used in cross-coupling reactions for the formation of C-C, C-N, C-O, C-F, C-CF₃, and C-S bonds. It is air-, moisture-, and thermally stable and is highly soluble in a wide range of common organic solvents. Some of its unique features include lower catalyst loadings, shorter reaction time, efficient formation of the active catalytic species, and accurate control of ligand: palladium ratio.

Application

Pd catalyst for cross-coupling SPhos Pd G3 can be used as a precatalyst in the Suzuki–Miyaura catalyst–transfer polymerization (SCTP) reaction of a wide spectrum of monomers, including electron-rich to electron-deficient (hetero)arenes. It is also used as a catalyst in the formation of a Csp3–Csp2 bond between sterically hindered boronic hemiester and quinone diazide, which is the key intermediate step in the enantioselective synthesis of azamerone. ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.

For larger scale uses, product also available in powdered form (776246)
