31. 3 was classified into Group B-2 (weak, aldimine-selective).
32. -, etc.) increase aldehyde-selectivities. In the presence of large quantities of Lewis acids, both aldehydes and aldimines are activated and aldehyde-selectivities are increased. Similarly, small quantities of Lewis acids increase aldimine-selectivities. These expectations were actually confirmed by experiments.
