摘要

Alkyl bromides were obtained in high yield in the reaction of the corresponding alcohols with chlorotrimethylsilane/lithium bromide. The reaction wm equally applicable to primary, secondary, and tertiary alcohols as well as to allylic and benzylic alcohols. High regioselectivity was observed in related conversions in which hexamethyldisilane/pyridinium bromide perbromide was used. Tertiary alcohols, for example, were converted selectively ...
