When treated with lead tetraacetate, cyclopropylcarbinol and cyclopropylmethylcarbinol do not give β-fragmentation products resulting from the intermediate formation of cyclopropyl radicals; however, cyclopropylmethylcarbinol affords a small amount of a fragmentation product which arises from CαCβ bond cleavage involving removal of a methyl radical. In contrast, cyclobutylcarbinol undergoes β-fragmentation

LlBr catalyzes efficiently the dihydroxylation of alkenes to afford syn and anti diols with excellent diastereoselectivity depending upon the use of NaIO4 (30 mol %) or Phl(OAc)(2) (1 equiv), respectively, as the oxidants. The oxidation of non-benzylic halides has been achieved for the first time to afford the corresponding diols in excellent yields.
