(Chemical Equation Presented) The rhodium(I)-catalyzed methylenation of ketones using trimethylsilyldiazomethane proceeds to give the corresponding alkenes in good yields (60-97%). The use of an excess of 2-propanol and 1,4-dioxane as a solvent were instr

The isomerization of siloxycyclopropanes to enol silyl ethers and allyl silyl ethers was accomplished by using 2 as a catalyst.Regiochemistry with respect to the newly formed double bond of the product was highly dependent on the substitution pattern of cyclopropane ring.
Silyl Halides from (Phenylseleno)silanes. Reaction with Oxiranes and Alcohols To Give Hydrolytically Stable Silyl Ethers.

The preparation of (phenylseleno)silanes and their reactions with halogens (Cl2, Br2, I2) to give silyl halides and diphenyl diselenide are described.Highly hindered tert-butyldimethyl and tert-butyl diphenylsilyl halides were easily prepared.The reaction of silyl bromides and iodides with oxiranes followed by diazabicyclononane treatment gave allylic alcohol silyl ethers.Tertiary alcohols reacted rapidly with silyliodides to give hydrolytically stable silyl ethers.Treatment of the silyl ethers with tetra-n-butylammonium fluoride gave the free alcohols withoutrearrangement or isomerization.
Electrophilic Conversion of Oxiranes to Allylic Alcohols with tert-Butyldimethylsilyl Iodide
Detty, Michael R.
, p. 924 - 926 (2007/10/02)
tert-Butyldimethylsilyl iodide (I) is prepared from the reaction of iodine with (phenylseleno)-tert-butyldimethylsilane in acetonitrile.The reaction of oxiranes with 1 followed by treatment with 1,5-diazabicyclonon-5-ene gives accetable yields of allylic alcohols isolated as their tert-butyldimethylsilyl ethers.Ring opening involves cleavage of the bond to the more highly substituted carbon.
