โœฆ Synopsis

Desilylation of a series of hydrolytically stable hydroxyquinone t-butyldimethylsilyl ethers was achieved in high yields by the use of potassium fluoride in the presence of catalytic amounts of aqueous 48% hydrobromic acid (HBr), or basic aluminium oxide (Al 2 O 3 ), and tetra-n-butylammonium fluoride (Bu 4 NF) as cleaving agents.

Desilylation of t-Butyldimethylsilyl Ethers of Hydroxyquinones. -The most general of three applied different desilylating procedures is the cleavage of the O-Si bond with Bu 4 NF. The other two methods use KF as desilylating agent in either the presence of a catalytic amount HBr, or basic Al 2 O 3 .
