- Transformations of 3-carene oxide at rhenium-containing catalysts
-
The transformations of 3-carene oxide at rhenium-containing catalysts were studied.The introduction of rhenium into the catalytic system significantly increases the reaction rate and leads to the formation of compounds not previously encountered in the products from the isomerization of 3-carene oxide, i.e., 3-carene, 3(10),4-caradiene, 3,3,6-trimethylcycloheptanone, and 3-caren-10-ol.

- DISPROPORTIONATION OF HYDROGEN IN 3-CARENE
-
The disproportionation of hydrogen in 3-carene takes place with the formation of compounds of the 1,1,4-trimethylcycloheptane series.The proposed reaction mechanism involves dehydration of the 2-carene to 2,4-caradiene, which exists in a rapid tautomeric equilibrium with 3,7,7-trimethyl-1,3,5-cycloheptatriene.This gives rise to the appearance of compounds with a seven-membered ring in the reaction product.

- Chemistry of the 2-Pinanols. 2. Investigation of the Utility of the Enhanced Basicities of the Pinanoxide Bases
-
The utility of the alkoxides of cis- and trans-2-pinanol has been investigated.Yiels comparable to and exceeding those obtained with tert-butoxide are reported for the alkylation of ethyl acetoacetate, for the conversion of α-pinene oxide to trans-pinocarveol and cis-3-pinen-2-ol, and for the isomerization of vinylnorbornene and limonene.Dehydrohalogenation was effected rapidly on bornyl chloride and 2,6-dichlorocamphane-compounds reported to be inert to potassium tert-butoxide in tert-butyl alcohol.Reactions with 1-octyl bromide and with benzyl chloride showed that the pinanoxides have nucleophilicities comparable to that of tert-butoxide.
