An important form of heterogenous catalysis is phase transfer catalysis. The transfer of a reactant from one phase into another where reaction occurs is facilitated by using phase transfer catalysts. Studies reveal that benzoin condensation in aqueous media using quaternary ammonium salt (Q+X–) as pseudo phase transfer catalysts (Scheme 2.30) tend to be 100% atom economical (Yadav and Kadam, 2012).

The benzoin condensation is a reaction between two aromatic aldehydes, particularly benzaldehyde. The reaction is catalysed by a nucleophile such as cyanide anion or an N-heterocyclic carbene. The reaction product is an aromatic acyloin with benzoin as the parent compound (Adams and Marvel, 1941).

An efficient and simple one-pot procedure for the synthesis of α-diketones from a variety of aldehydes via benzoin condensation under the influence of a catalytic amount of DBU-NHC has been developed by Shimakawa et al. (Scheme 58) (75).
