Tetraacetate Oxidation of Cycloalkanols

The reaction of lead tetraacetate (LTA) with monohydric alcohols produces functionalization at a remote site yielding derivatives of tetrahydrofuran (THF) 12). An example is the reaction of 1-pentanol with LTA in nonpolar solvents which produces 30% THF. The reaction, which is believed to proceed through free-radical intermediates, gives a variable distribution of oxidation products depending on solvent polarity, temperature, reaction time, reagent ratios, and potential angle strain in the product. [Pg.11]

In the procedure given here, the reaction is applied to a cyclic alcohol to produce a bridged ether. The product is of interest in that it can be cleaved to produce disubstituted cyclooctanes of known geometry (cf. Chapter 6, Section V). [Pg.11]
