Ring-opening of oxiranes, oxetanes and other cyclic ethers

3 Ring-opening of oxiranes, oxetanes and other cyclic ethers 

By far the most important reactions in this category are those of oxiranes, and the reaction with the parent compound is a good general method for two-carbon homologation  

The early Organic Syntheses procedure for the synthesis of hexan-l-ol [24] is typical, but suffers from the disadvantage of using benzene as a cosolvent, as
