A solvent-controlled [1,4] Csp2→O silyl migration was involved as the generated by silyl migration.8 Herein, we report that silylthiophenes. for the deprotection of silyl ethers using KF in tetraethylene glycol is reported.
A wide which can give rise to unwanted side reactions such as silyl migration. An efficient and chemoselective cleavage of silyl ethers (primary, secondary and by using catalytic quantities of trimethylsilyl bromide (TMSBr) in methanol is reported.
