- Microwave specific Wolff rearrangement of α-diazoketones and its relevance to the nonthermal and thermal effect
-
α-Diazoketones possess high electric dipole moments, as a consequence of the dipolar nature of the diazocarbonyl functional group. The vectorial analysis, theoretical calculations (PM3 and ab initio), and literature reports based on experimental and theor

- STRUCTURE AND PROPERTIES OF THE PRODUCTS FROM THERMAL CYCLIZATION OF 1-ACETOXY-3,7-DIMETHYL-1,2,6-OCTATRIENE
-
2-Acetoxymethyl-3-isopropenyl-1-methylcyclopentene, 5-acetoxymethylene-1,6,6-trimethylbicyclohexane, and 2,6,6-trimethyl-exo- and 2,6,6-trimethyl-endo-7-acetoxybicyclohept-1-enes with a double bond at the "bridgehead" were obtained by thermal cyclization of 1-acetoxy-3,7-dimethyl-1,2,6-octatriene.The products are oxidized unusually readily by atmospheric oxygen with the formation of the unsaturated 1-hydroxy derivatives.Hydrolysis of the thermal cyclization products gave the corresponding hydroxy and oxo compounds, and their characteristics were studied.The geometry of the 1-hydroxy-2,6,6-trimethyl-endo-7-acetoxybicyclohept-2-ene molecule was determined by the X-ray crystallographic method.
