Trimethylsilyl and tetrahydropyranyl ethers were easily converted into their corresponding bromides and iodides with high
efficiency and selectivity by N-bromo- and N-iodosaccharins in the presence of triphenylphosphine under neutral conditions. The
reaction of trimethyloctyloxysilane as a model compound was studied in different solvents with different ratios of silyl ethers,
triphenylphosphine and N-halosaccharin at room temperature, in order to optimize the reaction conditions.
