cleaved by nickelboride allowing regeneration of corresponding carbonyl compounds. Optimum reaction conditions have also been defined to obtain alcohols exclusively by reduction of oxathiolanes. Reactions are rapid at room temperature and do not require protection from atmosphere. Mild reaction conditions, simple work up, and high yields are some of the major advantages of the procedure.

Highly efficient interconversion of a range of 1,3-oxathiolanes, 1,3-dithiolanes and 1,3-dithianes to their acetals at ambient temperature using N-bromosuccinimide or N-chlorosuccinimide and different types of alcohols and diols was investigated.
Silica-Gel Supported Sulfamic Acid (SA/SiO<sub>2</sub>) as an Efficient and Reusable Catalyst for Conversion of Ketones into Oxathioacetals and Dithioacetals
A simple and efficient method for the conversion of carbonyl compounds to oxathioacetals and dithioacetals using SA/SiO2 as an acid catalyst has been achieved. SA/SiO2 is easily recovered from the reaction mixture and can be reused at least 15 times without loss of catalytic activity.
