B. Boyer et al., INVERSE PHASE-TRANSFER CATALYSIS .1. REDUCTION OF KETONES IN A MICELLAR 2-PHASE MEDIUM, New journal of chemistry, 19(7), 1995, pp. 807-811
The reduction reaction of ketones by sodium borohydride has been inves
tigated in a two-phase medium using an inverse phase-transfer catalysi
s (IPTC) technique in the presence of surfactants (monomeric and polym
eric species). The phase transfer process is always catalyzed by micel
lar aggregates. The main role of the surfactant is to promote the tran
sfer of the lipophilic substrate into the water phase.
