The all-silica zeolite RUB-41, containing 8- and 10-membered rings, is able to separate trans-2-butene and cis-2-butene from 1-butene and represents a possible improvement in isolating pure 1-butene from a butene mixture.

Aziridines from ammonia: Unprotected aziridines are formed from styrenes in one catalytic step. Ammonia is incorporated directly using an aqueous micellar solution containing bleach as oxidant and sub‐stoichiometric amounts of iodide (see picture).
