Usage

General Description

1-Methylcyclooctanol is a colorless liquid with a mild, somewhat peppery odor. It is a member of the cycloalkanol class of chemical compounds, which are cycloalkanes with a hydroxyl group attached to one of the carbon atoms. 1-Methylcyclooctanol is used as a flavoring agent and fragrance ingredient in various products, including perfumes, soaps, and household cleaners. It is also used as a solvent in chemical reactions and as an intermediate in the synthesis of other organic compounds. Additionally, it has some potential use as a pesticide and insect repellent. However, it is important to handle 1-methylcyclooctanol with caution, as it can be harmful if ingested or inhaled, and it may cause skin and eye irritation.

Regiodivergent Hydroborative Ring Opening of Epoxides via Selective C-O Bond Activation

A magnesium-catalyzed regiodivergent C-O bond cleavage protocol is presented. Readily available magnesium catalysts achieve the selective hydroboration of a wide range of epoxides and oxetanes yielding secondary and tertiary alcohols in excellent yields and regioselectivities. Experimental mechanistic investigations and DFT calculations provide insight into the unexpected regiodivergence and explain the different mechanisms of the C-O bond activation and product formation.

Acid-Catalyzed Olefin-Alcohol Interconversion in the 1-Methylcyclooctyl System. Strain-Relief Acceleration of the Hydration of 1-Methyl-trans-cyclooctene

Rates of reaction with aqueous perchloric acid at 25 deg C have been measured for 1-methyl-cis-cyclooctene, 1-methyl-trans-cyclooctene, and their exo isomer, methylenecyclooctane.The only products formed to any significant extent in each of these reactions are 1-methylcyclooctanol and the cis-cycloalkene, but both the trans- and exo-olefins give these products in initially noneequilibrium proportions: / = 1.27 +/- 0.05 at equilibrium, 15.1 +/- 0.9 from the trans-olefin and 0.44 +/- 0.05 from the exo-olefin.This is taken as evidence for the existence of two conformationally different 1-methylcyclooctyl carbocationic intermediates in these reactions, an unstable crown (or twist) cation formed by protonation of the trans-olefin and a (conformationally) stable boat-chair cation formed from the other two olefins and the alcohol.The barrier for interconversion of these two cations is estimated at ΔG(excit.) = 5.3 +/- 0.6 kcal mol-1.The barrier for hydration of either cation to the alcohol is also estimated, by two different methods, at ΔG(excit.) = 3.6 +/- 0.6 kcal mol-1 or 4.3 +/- 0.3 kcal mol-1.The smallness of these barriers suggests that the reaction of tertiary aliphatic carbocations with water in aqueous solution is an essentially unactivated process.These estimates plus the rate and equilibrium constants measured here allow nearly complete free energy characterization of the 1-methylcyclooctyl system.The rates of reaction of the cis- and exo-olefin with the hydronium ion are normal, but strain relief accelerates the rate of the trans-cycloalkene by a factor of 18500.
