Application

PCy3 Pd G2 is a monophosphine-coordinated 2-phenylaniline-based palladacycle complex that can be used as a precatalyst:
  • To prepare diarylmethanes by Suzuki cross-coupling reaction with heterocyclic-chloromethyl derivatives with aryl/heteroaryl boronic acids.
  • To synthesize poly(arylene)s by the Suzuki cross-coupling polymerization reaction between aryl dihalides and aryldiboronic acids.
  • In the C-H bond functionalization reactions.

A comprehensive understanding of the C-H bond cleavage step by the concerted metalation-deprotonation (CMD) pathway is important in further development of cross-coupling reactions using different catalysts. Distortion-interaction analysis of the C-H bond cleavage over a wide range of (hetero)aromatics has
