Tin(ii)hydroxychloride is reported as a heterogeneous Bronsted acid catalyst. Sn(OH)Cl was synthesized by a precipitation method and characterized by XRD, FT-IR, ¹H MAS NMR, SEM, TG-DTA and N₂ sorption. The acidity measurements of tin(ii)hydroxychloride by FT-IR pyridine adsorption and ¹H MAS NMR showed the presence of Bronsted acidity. The Bronsted acidity can be attributed to strong hydrogen bonding between the -OH and Cl groups. Sn(OH)Cl showed high activity for important condensation reactions such as the Prins condensation, Claisen-Schmidt condensation and ketalization. The catalytic activity of Sn(OH)Cl was compared with that of SnO, SnO₂ and Sn₂(OH)₂O. The catalyst was recycled three times with a negligible decrease in activity.

Enantioselective microbial hydrolysis of C₁ and C₂ dissym. cyclic carbonates with disubstitution (Me and another groups) has been developed. Pseudomonas diminuta (FU0090), a bacterium, efficiently catalyzes the hydrolysis of five-membered cyclic carbonates. While the trans-substrates are hydrolyzed with low enantioselectivities and/or reactivities, the microbe hydrolyzes the cis-substrates with very high enantioselectivities to afford the corresponding almost optically pure anti-(2R,3S)-diols. On the other hand, six-membered trans-cyclic carbonates are enantioselectively hydrolyzed to afford the corresponding optically active syn-(2R,4R)-diols, although the hydrolysis of the cis-substrates gives racemic compounds In all cases, the enzyme prefers the (R)-enantiomer for the carbon atom bearing a Me group.
