Acetals are obtained in good yields by treatment of aldehydes and ketones with trialkyl orthoformate and the corresponding alcohol in the presence of 0.1 mol % Bi(OTf)3·4H2O. A simple procedure for the formation of acetals of diaryl ketones has also been developed. The conversion of carbonyl compounds to the corresponding 1,3-dioxolane using ethylene glycol is also catalyzed by Bi(OTf)3· 4H2O (1 mol %). Two methods, both of which avoid the use of benzene, have been developed.

Thurkauf, Andrew,Jacobson, Arthur E.,Rice, Kenner C.
, p. 233 - 234 (2007/10/02)
Acetals of diaryl ketones with nitro, halo and methoxy substituents are easily prepared in high yield by treatment with an alcohol and the corresponding trialkyl ortoformate in the presence of catalytic amount of trifluoromethanesulfonic acid.
