A. Soriente et al., K10 montmorillonite catalysis - C-C bond formation by catalyzed conjugate addition and alkoxyalkylation of 1,3-dicarbonyl compounds, GREEN CHEM, 1(3), 1999, pp. 157-162
The intrinsic catalytic properties of K10 and KSF montmorillonites allow th
e achievement of more environmentally acceptable procedures for C-C bond fo
rmation: Michael addition and alpha-alkoxyalkylation of 1,3-dicarbonyl comp
ounds are performed by a convenient and cheap procedure based on the employ
ment of montmorillonites as heterogeneous, reusable catalysts.
