Two Component Reaction needs equal number of reactants?


I'm trying to simulate a Suzuki coupling using the Two Component Reaction node. This works as long as the number of reactants for the 2 reactant ports are the same, but fails if they are unequal (e.g. one bromide to react with a large number of boronic acids):

WARN      RDKit Two Component Reaction       Number of second reactants is lower than number of first reactants.

Seems like a bug to me.

Kind regards,


Make sure you select "Do MAtrix Expansion", otherwise only the reactants on the same row are reacted with each other. 


Much better, thank you!
