Table 1 Three-component ARC union of cuprate or dithiane nucleophiles, linchpin 7and a series of electrophiles. A series of experiments were carried out to track the formation of each intermediate during the three-step LR-ARC sequence. Jump to site search.
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. which can give rise to unwanted side reactions such as silyl migration .
We next turned to exploring the viability of exploiting the derived LR-ARC anions in cross-coupling reactions Table 2.
