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 fluori
Recently, reports have appeared which describe the cleavage of diethyl ether with highly electrophillc tetrachlorobenzyne and tetrafluorobenzyne to give ethylene and the corresponding 2,3,4,5-tetr&alophenetole. 192 Although unsubstituted benzyne is thought to undergo nucleophlllc attack by ethers to
