Microwave‐Assisted Protection of Phenols astert‐Butyldimethylsilyl (TBDMS) Ethers Under Solvent‐Free Conditions
摘要:
A facile, time-saving procedure to protect phenols with tert-butyldimethylsilyl chloride using imidazole as catalyst under solvent-free conditions is described. Several phenolic compounds with different substitution patterns can be silylated in high yield with substantially reduced generation of residues, a present goal in organic synthesis.
