SiCl4 + ECHO HgSiCl + H2SiCl2 + other products... [Pg.24]

SiCl4, TFA, anisole. SiCl4 serves to reduce the sulfoxide prior to acid-catalyzed cleavage. Other sulfoxide reducing agents could probably be used. [Pg.340]

Nal, SiCl4, rt, 20-60 min, 78% yield. Cleavage results in subsequent formation of a diiodide, but this is not a general process. For the most part, ketals are cleaved to give the ketone, while catechol methylene acetals return the catechol. ... [Pg.202]

Tetramethylene sulfoxide, TMSOTf, 4°, 4 h, 87% yield or Ph2SO, MeSiCl3 or SiCl4, TFA, 90-96% yield. The latter conditions also cleave the Acm, Bn, MeOBn, and MeBn groups. In all cases, disulfides are isolated. ... [Pg.470]

Since sulfides tend to react with electrophiles, a method for protecting sulfides could be quite useful. Sulfoxides can be used to protect sulfides and are easily formed by a variety of oxidants. Sulfides can be regenerated with thiols, SiCl4 (0°, 15 min, TFA, anisole), LiBH4/Me3SiCl, and DMF SO3/HSCH2CH2SH (DMF, Pyr, rt, 85% yield)." ... [Pg.491]

M SiCl4, 3 M phenol, CH2CI2, 10 min. The Fmoc, Cbz, and Bn ester and ether groups were not noticeably cleaved even after 18 h of exposure." ... [Pg.521]
