Published: July 2006

Abstract
Photo-reduction of p-benzoquinone and its methyl- or chloro-derivatives has been investigated using the CIDNP technique. Strongly polarized PMR signals due to p-benzoquinones themselves, active reaction intermediates and hydroquinones were observed during the course of the reactions. From these results, the reaction scheme of these photo-reductions was proposed.

THE THERMAL CYCLIZATION OF 8-(2,2-DISUBSTITUTED VINYL) HEPTAFULVENES LEADING TO AZULENE DERIVATIVES
Authors: Tsuruta Haruki , Sugiyama Takekatsu , Mukai Toshio 
Published: July 2006

Abstract
Pyrolysis of 8-(2,2-dicyano-)-(3) and 8-(2-cyano-2-methoxycarbonylvinyl) heptafulvenes (5) afforded 1,2- or 1,3-disubstituted azulenes (6–9). The formation of such azulene derivatives could be explained in terms of thermally allowed ten electron-participating ring closure followed by 1,5-sigmatropic migration of cyano and/or methoxycarbonyl group(s).

Authors: Mukaiyama Teruaki , Ueki Masaaki , Izawa Toshio , Kuwahara Mikio 
Published: July 2006

Abstract

By this modified procedure various aromatic compounds including chlorobenzene were alkylated at room temperature in high yields. When trioxane was used as alkylating source, diphenylmethane was obtained in excellent yield without accompanying the formation of dibenzyl ether. Based on this finding, it was shown that C–O bond of the benzyl ether was cleaved under the very mild conditions by this couple.

Published: July 2006

Abstract
In order to apply mass spectrometry to metal complex chemistry, the mass spectra of oxinates of divalent metals (Zn, Cu, Ni, Co and Mn) were measured and the fragmentation of oxinates were investigated.

The stabilities of metal oxinates against electron impact have been considered.

The hydrogenation of ethyl 2-methyl-1-cyclohexenyl ether with platinum metal catalysts yields saturated cis-ether with high stereospecificity in ethanol. Formation of the trans-ether during the course of hydrogenation arises through isomerization to ethyl 6-methyl-1-cyclohexenyl ether which yields both cis- and trans-ethers on hydrogenation.
