A microstructured mesh contactor that can offer residence time of more than minutes is used for gas–liquid–solid hydrogenations and gas–liquid asymmetric hydrogenations. Applications for catalyst/chiral inductor screening and for kinetic data acquisition are demonstrated.

1–2 nm Pt nanoparticles and Karstedt's catalyst were used in the hydrosilylation of 1-octene with a polymethylhydrosiloxane and showed a very similar behaviour (the same TONs and the same selectivity towards 1-octene isomerization). This further assesses that Karstedt's catalyst is not truly homogeneous, but rather colloidal, during catalysis at high TONs.
