The alkylation of resorcinol with cyclic allylic alcohol in non-aqueous acid medium gives intermolecular Friedel-Craft compounds. The products are primary alkylation products. The likage always occurs between carbon 3 of cyclic allylic alcohol and the position 2, 4, 5 or 6 of the resorcinol.

Four coordinated rhodium(Ⅰ) complexes, Rh($ClO_4$)(CO)$(PPh_3)_2$ and [$Rh(CO)(PPh_3)_3$]$ClO_4$(2) catalyze the iosmerization of allylic alcohols to the corresponding carbonyl compounds at room temperature under nitrogen. The isomerization is faster with 2 than with 1, which is understood in terms of relative ease of the last step of the catalytic cycle, the reductive elimination of enol. Relative rates of the isomerization with 1 and 2 for different allylic alcohols are also explained by the relative ease of the enol elimination step in part. The first step of the catalytic cycle, the complex formation of the allylic alcohol through the ${\pi}-system$ of the olefinic group of the allylic alcohol and the following step, formation of hydridoallyl complex also seem to affect the overall rate of the isomerization.

(C₄H₄N₂H)₂Cr₃O₁₀ has been prepared by the reaction of C₄H₄N₂ with CrO₃ in water. (C₄H₄N₂H)₂Cr₃O₁₀ was identified by elemental analysis, IR, UV-Vis and TG-DTA-TMA system. The oxidation of benzyl alcohol by (C₄H₄N₂H)₂Cr₃O₁₀ in organic solvents showed that the reactivity increased with the increase of the dielectric constant. The oxidation of alcohols was examined by (C₄H₄N₂H)₂Cr₃O₁₀ in CH₂Cl₂. As a resuit, (C₄H₄N₂H)₂Cr₃O₁₀ was found as efficient oxidizing agent that converted benzylic alcohol, allylic alcohol, saturated primary alcohol, secondary alcohols to the corresponding aldehydes or ketones(70%~96%). The selective oxidation of alcohols was also examined by (C₄H₄N₂H)₂Cr₃O₁₀ in CH₂Cl₂. (C₄H₄N₂H)₂Cr₃O₁₀ was selective oxidizing agent(10%~96%) of benzylic alcohol, allylic alcohol, saturated primary alcohols in the presence of secondary ones. In the presence of DMF. solvent with acidic catalyst such as HCl. (C₄H₄N₂H)₂Cr₃O₁₀ oxidized benzyl alcohol and its derivatives. The Hammett reaction constant was -0.70(303K). The observed experimental data were used to rationalize the hydride ion transfer in the rate determining step.

(2S,3R)-3-Hydroxy-2-(hydroxymethyl)-3,6-dihydro-2H-pyridine 8, an important precursor for the synthesis of polyhydroxylated piperidine azasugars, has been prepared from L-serine. Highly stereoselective nucleophilic addition to amino aldehyde 5 gave the corresponding allylic alcohol 6 which proceeded to give dihydro-2H-piridine 7a via a Grubbs II catalyzed RCM. Stereoselective H-bond directed epoxidation of allylic alcohol led to the oxiranyl alcohol 9 which was easily converted to L-deoxyaltronojirimycin by regioselective ring opening.

An efficient and inexpensive method for the substitution of allylic hydroxyl group with fluoride, without allylic rearrangement, and elimination was developed. This method consists of treating an allylic alcohol with methylithium, followed by p-toluene sulfonyl fluoride, lithium fluoride and 12-Crown-4. This methodology was proved to be efficient by preparting geranyl fluoride, neryl fluoride, cinnamyl fluoride, E, E-farnesyl fluoride, retinyl fluoride and 4-fluoro-2-methyl-6-(ptolyl)-2-heptene.
