Enzymatic hydrolysis of acylals. A promising route to chiral aldehydes
Angelis, Yiannis S.,Smonou, Ioulia
, p. 8109 - 8112 (1997)
A new and convenient method for the optical resolution of aldehydes through a lipase-catalyzed resolution of the corresponding acylals has been developed. Candida rugosa Lipase (CRL) showed the best stereoselectivity.

A novel, mild, and chemoselective method was developed for the preparation of gem-diacetates from aldehydes and acetic anhydride in the presence of titanium(IV) fluoride (1-5 mol%) under solvent-free conditions at room temperature. The reaction showed a high chemoselectivity toward aldehydes in the presence of ketones. Moreover, titanium(IV) fluoride also catalyzed the deprotection of gem-diacetates to the corresponding aldehydes in water. This efficient and simple method has several benefits, including the use of an inexpensive catalyst, solvent-free conditions, mild reaction temperatures, and high yields, which make it both cost-effective and environmentally friendly.

Sonochemical switching from Ionic to Radical Pathways in the Reactions of Styrene and trans-β-Methylstyrene with Lead Tetraacetate
Ando, Takashi,Bauchat, Patrick,Foucaud, Andre,Fujita, Mitsue,Kimura, Takahide,Sohmiya, Hajime

The reactions of sryrene and trans-β-methylstyrene with lead tetraacetate in acetic acid are greatly influenced by ultrasonic irradiation to give products resulting mostly from radical chain pathways, whereas mechanical agitation gives products only from ionic processes.
