Scaling relations in homogeneous catalysis: Analyzing the buchwald-hartwig amination reaction
Scaling relations are widely used to study surface reactions. However, the exploration of its utility in homogeneous catalysis is currently far less reported. In this work, we have investigated the transferability of the concept of scaling relations to a homogeneous catalysis reaction known as the Buchwald-Hartwig amination (BHA) reaction. The reaction of PhBr with MeNH2 using 37 different Pd-L complexes (L = phosphine ligand) is studied, and scaling relations are established among the reaction intermediates and transition states. Using the scaling relations, we construct volcano plots, which is the plot of the log(rate) vs the descriptor intermediate energy. The insights from the volcano plots agree well with the experimental trends from the literature and give direction toward better catalyst design.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Quality Control of: 2-(Di-tert-Butylphosphino)biphenyl, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 224311-51-7, in my other articles.
