Alkyl dimethylsilyl ethers

Recently, alkyl dimethylsilyl ethers (58) have been found to serve as bifunctional reagents for a similar reductive etherification, in which (58) function as both reducing agents and oxygen nucleophiles under catalysis by Me3SiI (Scheme 9.33)... 

Octakis (2,3,6-tri-0-methyl-gamma-cyclodextrin) was used to separate enantiomers of methyl esters of deltametrinic acid and permetrinic acid the positional isomers of nitrotoluene were also separated on the same column [17,18]. Various alkyl- and dialkyl-benzenes have been separated on beta- and gamma-cyclodextrin [19]. A complete review of the use of cyclodextrins in chromatography has been published by Hinze [20]. Cyclo-dextrins have been analyzed by packed-column gas chromatography as their dimethylsilyl ethers [21].

High yields of seven-membered rings can be achieved by treating ally] acetates with Lewis acids. The dimethylsilyl enol ether exclusively attacks the least alkylated terminus of the initial allyl cation3.
