Regiospecific Synthesis of Allylic Dimethylmethoxysilanes
Tzeng, Dongjaw,Weber, William P.
, p. 693 - 696 (1981)
Photochemically generated dimethylsilylene reacts regiospecifically with allylic methyl ethers to yield allylic dimethylmethoxysilanes.Reaction of allylic methyl ethers with dimethyldichlorosilane and sodium metal likewise gives allylic dimethylmethoxysilanes in preparatively useful yields.Regiospecificity, however, is not always observed in this latter reaction.Such allylic dimethylmethoxysilanes can be converted to allylic trimethylsilanes easily by reaction with methyllithium.

Allylic and benzylic alcohols are converted into corresponding unsymmetrical ethers when reacted with various orthoesters in the presence of montmorillonite KSF at ambient temperature. A detailed study has been undertaken to examine the mechanism and generality of these reactions with regard to various acidic catalysts, which reveal interesting competitive reactions mainly O-acetylation, together with trace amount of dimerized product. The type of the side product and their relative quantity depends upon the nature of the catalyst employed. Furthermore, the low yields of the Claisen rearrangement product obtained from allylic alcohols under heating is rationalized due to the formation of some of these products.

Kumar, H. M. Sampath,Reddy, B. V. Subba,Mohanty, Pradyumna K.,Yadav
, p. 3619 - 3622 (2007/10/03)
Montmorillonite KSF catalyzes the selective O-alkylation of various primary allylic and benzylic alcohols when reacted with different orthoesters at room temperature to afford ethers in moderate to high yields.
