Description

In combination with PPh3, can be used to convert alcohols and THP ethers to bromides with inversion of configuration. It is a versatile catalyst for acetalization and transacetalization of carbonyl compounds, preparation of acetonides from epoxides, and acylals from aldehydes. It is employed for selective monobromination of imidazoles and indoles
