Description

Application

• Propionitrile (PPN) is an effective solvent for catalytic asymmetric aldol reaction of a silyl enol ether with aldehydes in the presence of a chiral tin(II) Lewis acid catalyst.
• The co-solvent formed by mixing PPN with acetonitrile can be used to fabricate polymer gel electrolytes (PGEs) of dye-sensitized solar cells (DSSCs), which lead to enhanced stability of gel-state DSSCs.
• PPN can be used as a solvent for the Brønsted acid-catalyzed synthesis of N-alkyl cis-aziridines via [2+1] annulation of a diazo compound formed by the combination of an acetate and enolate. The process does not involve the use of metals or reagents and only atomic nitrogen as a co-product.
