If you have helped develop processes to prepare an API, you have certainly come across catalytic reactions such as C-C or C-N cross couplings, homogeneous catalytic hydrogenations, olefin metathesis reactions, carbonylations and the like. The literature is full of accounts showing that these reactions are difficult to scale up, and sometimes fail in the plant; therefore, it is likely you have experienced these problems. What makes these reactions so difficult to scale up is the fact that the catalysts are unstable and their presence cannot be monitored by the traditional methods, at least if the catalyst is used in very small amounts, which is always the case in a practical catalytic reaction. Therefore, one must resort to some level of kinetic analysis.

With some understanding of the rate law, you will be able to rationally affect important parameters like resting state of the catalyst and rate-determining step; you will be able to select the best ligand at the right concentration for a high-turnover process, you will learn to eliminate performance-limiting off-cycle species, and select the best auxiliary reagent at the appropriate concentration. Many examples will be provided, showing how a certain level of kinetic analysis contributed to a successful scale up, or how such analysis would have helped develop a better process. Specific approaches used to obtain kinetic information will be discussed, including a powerful tool called Reaction Progress Kinetic Analysis (RPKA). All these analyses require surprisingly little effort and theoretical sophistication.

The course will demonstrate that some basic level of kinetic analysis can help optimize the reactions and make them more robust, helping you transfer efficient processes to the plant with increased confidence.

  • Basic concepts: turnover frequency, turnover number, catalyst resting state, rate-determining step
  • Why are catalytic reactions so difficult to scale-up?
  • Why do we need (some) kinetic information?
  • Simple kinetic laws and how to obtain them

Benefits of Attending

arrow

You will acquire useful information to develop a catalytic reaction without delving into complex physical chemistry. You will develop tools to optimize and make your reactions robust, so that you will be successful in transferring them to the pilot plant and beyond.

Who Should Attend

arrow

Anyone interested in developing practical catalytic reactions using organometallic chemistry. Ideal for less experienced process chemists, but also for those with many years of experience who would like to learn to scale up catalytic reactions with more confidence. It can be useful also to medicinal chemists who need to carry out their catalytic reactions on larger scale.
