Typical … WebbIt is known that appropriate groups Z in compounds of the type (Me 3 Si) 2 (ZMe 2 Si)CSiR 2 X can provide anchimeric assistance to the leaving of X − in reactions with electrophiles, including Ag(I) and Hg(II) salts , ICl [2], CF 3 CO 2 H and CF 3 CH 2 OH .
WebbBu2Sn(OMe)2 is reported to work better than Bu2SnO in the monoprotection of diols. The monoprotection of diols at the more hindered position can be accomplished through the stannylene if the reaction is quenched with PhMe2SiCl (45-77% yield).Microwave heating has been found to be effective for this transformation in some cases. ...
