Digital Reaction Optimization with Catalexis

Smarter Chemistry, Faster Results

What if catalyst and ligand screening for complex cross-coupling reactions could be predictable, fast, and AI-driven instead of relying on traditional trial and error workflows? Catalexis delivers exactly that by combining AI driven catalyst optimization, BayBE Bayesian modeling, and a curated 23 ligand phosphine plate to enable smarter, more efficient screening for transformations such as Buchwald-Hartwig aminations and Suzuki–Miyaura couplings.

Built for both traditional benchtop chemistry and high-throughput experimentation (HTE), Catalexis enables researchers to explore reaction space digitally, reduce experimental burden, and accelerate the identification of high performing ligands in cross-coupling reactions, and other sensitive transformations where small parameter shifts impact yields and selectivity.


How does Catalexis work?

Step 1 - Order Your Catalexis Kit

Step 1: Order Your Catalexis Kit

Choose the format that suits your workflow:

50 mg Ligand Kit - 23 phosphine ligands + Pd source + 5 portal tokens.   

1 µmol Screening Plates - five plates (23 ligands each) + Pd source + 5 portal tokens.

Step 2 - Run Your 23‑Ligand Screening Reactions

Run your 23‑ligand screen using your chosen substrate and conditions, keeping all variables constant. Compatible with manual setups and automated HTE workflows.

Step 3 - Upload Your Reaction Results to the Catalexis Portal

Upload your reaction yields (0 -100) into the Catalexis portal and redeem 1 token to receive your top ligand candidates. No chemistry metadata needed.

Step 4 - Generate AI Driven Ligand Rankings Driven Ligand Rankings

Catalexis compares your data against its database of 400+ ligands and highlights top performers. 

Step 5 - Optimize With Guided Recommendations

Define your reaction parameters and let the BayBE (Bayesian back-end) ML engine propose  the most promising next experiments within your chemical space, thereby, allowing you to sample the chemical space more efficiently than traditional DOE approaches.

Step 6 - Explore the Reaction Space with BayBE

Upload your new results and instantly receive suggested next conditions to continue improving yield

Step 7 - Repeat to Refine Results

Iterate steps 5-6 until your reaction achieves the desired target, be it yield, conversion, byproduct limitation or other custom variable.

User Testimonials

Discover how Catalexis is transforming labs – here’s what chemists are saying about their experience:

“Catalexis significantly streamlined our di-amination reaction optimization of 1,3-dichlorobenzene, saving time by providing a curated set of ligands to screen. After three rounds of screening, we identified the best ligand for our final industrial-scale process.”

Pharma Biotech Process Development Lab

“The suggested ligands delivered excellent results, including some I hadn’t initially considered trying.”

Academic Medicinal Chemistry Lab

"Catalexis is a nice tool wherein a kit of 23 ligands has the potential to evaluate and predict the performance of around 500 ligands with the help of AI."
